In the present investigation, the selective recovery of nickel from a leach solution of delaminated metal clads from obsolete mobile phone PCBs using the industrial reagent ACORGA M5640 has been studied. As a first step, copper is selectively separated from the mixed metal leach liquor by solvent extraction at pH 2, to leave a nickel-rich raffinate solution A second stage solvent extraction process conducted at pH 8 then permits recovery of the nickel. Small quantities of zinc and cadmium are also co-extracted In this study, the conditions for most suitable nickel extraction and stripping have been explored. Results indicate that quant. extraction of nickel (99.7%) can be achieved using a 1:5 organic (10 vol% extractant in kerosene) to aqueous (pH 8) phase ratio in 60 min. The nickel in the organic phase is readily stripped from the extractant, with more than 95% recovered, along with low levels of zinc (1.7 mg/L) and cadmium (0.6 mg/L), following a 0.5 M hydrochloric acid or 1 M nitric acid strip step. Cyclic usage of the extractant organic layer revealed that its effectiveness to extraction has remained equivalent to the first cycle. Finally, the separation of trace elements such as lead, tin and cadmium from the raffinate of stage 2 solvent extraction is also studied by cementation with zinc powder. The study reveals that the removal of these elements and the generation of pure zinc solution can be obtained by adding 300% excess zinc powder (74 μm) at 50 °C with 500 rpm stirring speed in 60 min. The separation of copper in stage 1, nickel from copper-free aqueous solution in stage 2 and other minor elements from the raffinate of stage 2 solvent extraction ensures the proposed process is sustainable and avoids complexity in the sequential metal recovery processes. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Application of 20427-59-2).

Toward High-Performance CO2-to-C2 Electroreduction via Linker Tuning on MOF-Derived Catalysts was written by Chen, Rongzhen;Cheng, Ling;Liu, Jinze;Wang, Yating;Ge, Wangxin;Xiao, Chuqian;Jiang, Hao;Li, Yuhang;Li, Chunzhong. And the article was included in Small in 2022.Electric Literature of CuH2O2 This article mentions the following:

Copper (Cu)-based metal-organic frameworks (MOFs) and MOF-derived catalysts are well studied for electroreduction of carbon dioxide (CO2); however, the effects of organic linkers for the selectivity of CO2 reduction are still unrevealed. Here, a series of Cu-based MOF-derived catalysts is investigated with different organic linkers appended, named X-Cu-BDC (BDC = 1,4-benzenedicarboxylic acid, X = NH2, OH, H, F, and 2F). It is found that the linkers affect the faradaic efficiency (FE) for C2 products with an order of NH2 < OH < bare Cu-BDC < F < 2F, thus tuning the FEC2:FEC1 ratios from 0.6 to 3.8. As a result, the highest C2 FE of ≈63% at a c.d. of 150 mA cm-2 on 2F-Cu-BDC derived catalyst is achieved. Using operando Raman measurements, it is revealed that the MOF derives to Cu2O during eCO2RR but organic linkers are stable. The fluorine group in organic linker can promote the H2O dissociation to *H species, further facilitating the hydrogenation of *CO to *CHO that helps CC coupling.

The selective depression effect of dextrin on pyrite during the Zn-Fe sulfides flotation under low alkaline conditions was written by Sun, Xin;Huang, Lingyun;Wu, Dandan;Tong, Xiong;Yang, Siyuan;Hu, Bo. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2022.Reference of 20427-59-2 This article mentions the following:

As an environmentally friendly scale inhibitor, characterized by low cost, high efficiency and no secondary pollution, dextrin was utilized as a depressant in the flotation separation of mixed Zn-S concentrate The microflotation results clearly demonstrate that dextrin exerted a good inhibitory effect on pyrite and sphalerite could be separated successfully from pyrite in low alk. environment. The mixed mineral flotation results further indicate that sphalerite could be efficiently separated from its synthetic mixture with pyrite via the use of dextrin as the depressant in the pH range of 7-9. The contact Angle test shows that dextrin can be adsorbed on the surface of Cu-activated pyrite to enhance hydrophobicity, but not on the surface of Cu-activated sphalerite. The results of IR spectroscopy investigations and XPS analyses indicate that under low alkali conditions, copper ions activate sphalerite, and copper sulfide polysulfide forms on sphalerite surface without Cu(OH)2 formation. Cu(OH)2, Fe(OH)2 and CuS were generated on pyrite surface due to the activation of copper ions. The adsorption between dextrin and metal hydroxyl compounds was the main cause of pyrite inhibition, which is attributed to the hydrophilic hydroxyl group in the dextrin mol. According to these results, dextrin can be used as a selective depressant for pyrite during sphalerite flotation in low alk. environment. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Reference of 20427-59-2).

And the article was included in ACS Applied Nano Materials in 2022.Electric Literature of CuH2O2 This article mentions the following:

Solar steam generation provides an efficient, sustainable, and affordable strategy for freshwater extraction from seawater and wastewater to effectively deal with the water shortage crisis. However, it still faces poor durability because the salting-out effect always leads to a decrease in the evaporation rate at high salt concentrations To address this issue, we designed mushroom-like micro/nanostructured graphene nanosheets/copper sulfide nanowires (graphene/Cu7S4) on Cu foam with Janus-type wettability by in situ oxidation of Cu foam and precipitation conversion, followed by the dip-coating method. The superhydrophilic Cu7S4 nanowires are endowed with the function of water supply and thermal insulation, and the hydrophobic graphene nanosheets are granted with the function of light absorption and water evaporation Under one sun illumination, the graphene/Cu7S4 foam with Janus-type wettability exhibits a high water evaporation rate of up to 2.78 kg m-2 h-1 and long-term stability for brine evaporation The excellent performances are ascribed to a fast water supply and a salt-rejecting effect due to the capillarity forces and high porosity. This solar steam generation with the Janus-type wettability has broadened the potential applications of seawater desalination, wastewater purification, and sterilization.

And the article was included in Science of the Total Environment in 2022.Synthetic Route of CuH2O2 This article mentions the following:

In many important industries, such as the textile printing industry, a large amount of dye/salt wastewater is often discharged, which can destroy the ecol. environment of the water body. Membrane technol. has a great potential in the treatment of environmental problems caused by dye/salt wastewater. Polyvinyl alc. (PVA) nanofiltration (NF) membrane has a bright future in dye/salt wastewater treatment, however, works on this are rare. Herein, antibacterial PVA NF membrane incorporated with Cu(OH)2 nanowires for the dye/salt wastewater treatment is reported. The membrane was prepared via coating the solutions containing PVA, glutaraldehyde and Cu(OH)2 nanowires on the polyethersulfone ultrafiltration membrane. Cu(OH)2 nanowires has a diameter of 60 nm and was successfully introduced into the membrane. The introduction of nanowires improved the membrane hydrophilicity and roughness, which is conducive to the improvement of membrane flux. Membrane separation performance for one component solution and dye/salt solution were investigated. The introduction of Cu(OH)2 increases the flux of the membrane obviously (the highest increase is 178.78% from 21.49 to 38.42 L·m-2·h-1·bar-1, for NaCl solution as the feed). Besides, the membrane doped with nanowires also possessed a high dye/salt selectivity. For one component solution, the dye removal rate was over 97.00% while the salt rejection was low (the lowest was 13.18% (NaCl)). For the dye/salt solution, the dye (Congo Red) rejection kept at a high level (98.91%) and the salt (NaCl) rejection was still low (13.71%), while the flux was also high (37.56 L·m-2·h-1·bar-1). The performance is superior to that of many membranes reported in previous works. Moreover, the Cu(OH)2 nanowires endowed the membrane with an improved and high antibacterial property. The sterilization rate of Escherichia coli and Staphylococcus aureus reached more than 99.99%.

Electrochem. upcycling wastewater N such as nitrate (NO3–) and nitrite (NO2–) into an NH3 fertilizer is a promising yet challenging research topic in resource recovery and wastewater treatment. This study presents an electrified membrane made of a CuO@Cu foam and a polytetrafluoroethylene (PTFE) membrane for reducing NO3– to NH3 (NH3) and upcycling NH3 into (NH4)2SO4, a liquid fertilizer for ready-use. A paired electrolysis process without external acid/base consumption was achieved under a partial c.d. of 63.8 ± 4.4 mA cm-2 on the cathodic membrane, which removed 99.9% NO3– in the feed (150 mM NO3–) after a 5 h operation with an NH3 recovery rate of 99.5%. A recovery rate and energy consumption of 3100 ± 91 g-(NH4)2SO4·m-2·d-1 and 21.8 ± 3.8 kWh kg-1-(NH4)2SO4, resp., almost outcompete the industrial NH3 production cost in the Haber-Bosch process.

Electrochem. converting nitrate ions, a widely distributed nitrogen source in industrial wastewater and polluted groundwater, into ammonia represents a sustainable route for both wastewater treatment and ammonia generation. However, it is currently hindered by low catalytic activities, especially under low nitrate concentrations Here we report a high-performance Ru-dispersed Cu nanowire catalyst that delivers an industrial-relevant nitrate reduction current of 1 A cm-2 while maintaining a high NH3 Faradaic efficiency of 93%. More importantly, this high nitrate-reduction catalytic activity enables over a 99% nitrate conversion into ammonia, from an industrial wastewater level of 2,000 ppm to a drinkable water level <50 ppm, while still maintaining an over 90% Faradaic efficiency. Coupling the nitrate reduction effluent stream with an air stripping process, we successfully obtained high purity solid NH4Cl and liquid NH3 solution products, which suggests a practical approach to convert wastewater nitrate into valuable ammonia products. D. functional theory calculations reveal that the highly dispersed Ru atoms provide active nitrate reduction sites and the surrounding Cu sites can suppress the main side reaction, the hydrogen evolution reaction.

The high levels of heavy metals contained in residual water and the pollution generated by a large amount of unexploited agro-industrial waste are a serious problem for the environment and mankind. Therefore, in the present work, with the aim of treating and reducing the pollution caused by heavy metal ions (Pb, Cd, Zn and Cu), activated carbons (ACs) were synthesized from sugarcane bagasse (SCB) and orange peel (OP) by means of phys. – chem. activation method in an acid medium (H3PO4, 85 wt%) followed by an activation at high temperature (500 and 700°C). Thereafter, these materials were used to produce carbon foams (CF) by the replica method and to evaluate their adsorbent capacity for the removal of heavy metals from synthetic water. XRD, FTIR, DLS, BET, Zeta Potential (ζ), SEM-EDS and AAS were used to investigate their structures, surface area, pore size, morphol., and adsorption capacity. The results show that as-prepared CF have a second level mesoporous structure and AC present a micro-mesoporous structure with a pore diameter between 3 and 4 nm. The exptl. adsorption capacities of heavy metals showed that the CF from OP present a better elimination of heavy metals compared to the AC; exhibiting a removal capacity of 95.2 ± 3.96% (Pb) and 94.7 ± 4.88% (Cu) at pH = 5. The adsorption values showed that the optimal parameters to reach a high metal removal are pH values above 5. In the best of cases, the min. remaining concentration of lead and copper were 2.4 and 2.6 mg L-1, resp. The exptl. data for carbon adsorbents are in accordance with the Langmuir and BET isotherms, with R2 = 0.99 and the maximum homogenous biosorption capacity for lead and copper was Qmax = 968.72 and 754.14 mg g-1, resp.

Due to the wide applicability of copper-based nanoparticles (CBNPs), their long-term utilization could raise the toxicol. concerns owing to their potential persistence, accumulation, and relatively low soluble nature. The present study is focused on the dissolution behavior of com. procured CuO nanoparticles (NPs) in natural surface water system (pond water) and DI water at environmental concentration (1 mg/L) of CuO NPs. The dissolution of CuO NPs in DI water was higher than the pond water. Maximum dissolved Cu concentration in DI water and pond water was 0.054 and 0.035 mg/L, resp. However, the dissolution kinetics followed reverse trend. High rate of dissolution (i.e., 0.049 h-1) observed in pond water, whereas the dissolution rate was low in DI water (i.e., 0.034 h-1). The trend of dissolution in presence of humic acid was 10 mg/L > 100 mg/L > 1 mg/L. Addnl., the dissolution of CuO NPs increased with increasing the IS (i.e., KH2PO4 > CaCl2 > NaCl) and decreasing the pH (i.e., pH 9 < pH 7 < pH 5.7) of suspension. The speciation modeling using a Visual MINTEQ software showed the presence of various species of Cu in pond water such as Cu-DOC (80%), Cu2+ (4%), CuCO3 (aq) (9%), CuOH+ (6%), and Cu(OH)2 (aq) (1%). The exptl. half-life of CuO NPs varied from 2.4 to 36 h in different mediums which confirms the persistence nature of CuO NPs in natural water system.
