Removal of heavy metals and cyanide from gold mine waste-water by adsorption and electric adsorption

BACKGROUND: Cyanide leaching is the most widely used technology in the gold industry and this process produces large amounts of waste-water requiring treatment before returning to the environment. There are several established techniques available to treat such toxic waste but all have some disadvantages. This study considers the use of electrical adsorption treatment of a gold mine waste-water containing cyanide, high copper, iron, and thiocyanate content, as well as the precipitating liquid without iron. RESULTS: A cell fitted with carbon electrodes made from low grade coal was used in this study and using an applied voltage of 2.0 V, plate spacing of 1 cm, and adsorption time of 24 h, the electric adsorption process provided good results on the raw cyanide waste-water, with observed percentage removal of total cyanide (71.14), zinc (99.52) and iron (83.28). The liquid waste, following precipitation of the raw solution with zinc sulfate, was also studied and after 5 h the percentage removals of cupric ion were 90.63, 71.49 and 90.63, respectively. Analysis showed that in the process of electric adsorption, the ions in solution interacted by directional migration, enrichment precipitation and adsorption processes. CONCLUSIONS: Electrical adsorption provides a suitable process for the treatment of waste-waters from the cyanide leaching of gold.

Iron Complexes of N-Substituted Thiosalicylideneimines. Part 1. Synthesis and Reactions with Oxygen and Carbon Monoxide

Iron(II) complexes with N-substituted bidentate and tetradentate thiosalicylideneimines can be prepared by the reaction of bis(thiosalicylaldehydato)iron(II) with appropriate primary amines.The bidentate compounds show S = 2 spin states while a number of the tetradentate compounds have the unusual S = 1 state.The tetradentate complexes react with CO to form monocarbonyl complexes and with O2 to form FeIII mu-oxo-bridged derivatives.Some evidence is presented to support the preliminary formation at low temperatures of a dinuclear iron(III) peroxo-species as the precursor of the mu-oxo-compounds.Several spin-paired FeIII compounds containing SN2-bonded tridentate ligands are also reported.

Deep Ultraviolet Copper(I) Thiocyanate (CuSCN) Photodetectors Based on Coplanar Nanogap Electrodes Fabricated via Adhesion Lithography

Adhesion lithography (a-Lith) is a versatile fabrication technique used to produce asymmetric coplanar electrodes separated by a <15 nm nanogap. Here, we use a-Lith to fabricate deep ultraviolet (DUV) photodetectors by combining coplanar asymmetric nanogap electrode architectures (Au/Al) with solution-processable wide-band-gap (3.5-3.9 eV) p-type semiconductor copper(I) thiocyanate (CuSCN). Because of the device's unique architecture, the detectors exhibit high responsivity (?79 A W-1) and photosensitivity (?720) when illuminated with a DUV-range (peak = 280 nm) light-emitting diode at 220 muW cm-2. Interestingly, the photosensitivity of the photodetectors remains fairly high (?7) even at illuminating intensities down to 0.2 muW cm-2. The scalability of the a-Lith process combined with the unique properties of CuSCN paves the way to new forms of inexpensive, yet high-performance, photodetectors that can be manufactured on arbitrary substrate materials including plastic.

Two different 1D-chains in the structures of the copper(I) coordination polymers based on bidentate Schiff-base building units and thiocyanate anions as bridging ligands

The reaction of the bidentate Schiff-base ligands (3,4,5-MeO-ba)2en (L1) and (4-Me-ba)2en (L2) with Cu(SCN) in CH3CN yielded two copper(I) coordination polymers [Cu(L1)(SCN)]n (1) and [Cu(L2)(SCN)]n (2), which have been characterized by elemental analyses, IR- and 1H NMR-spectroscopy, and X-ray crystallography. The non-centrosymmetric structures of both Cu(I) complexes consist of an one-dimensional polymeric chain in which copper(I) ions are bridged by two thiocyanate groups bonding in an end-to-end fashion. The Cu(I)?Cu(I) separation is 5.604 A in 1 and 5.706 A in 2.

Halo and Pseudohalo Cu(I)-Pyridinato Double Chains with Tunable Physical Properties

The properties recently reported on the Cu(I)-iodide pyrimidine nonporous 1D-coordination polymer [CuI(ANP)]n (ANP = 2-amino-5-nitropyridine) showing reversible physically and chemically driven electrical response have prompted us to carry a comparative study with the series of [CuX(ANP)]n (X = Cl (1), X = Br (2), X = CN (4), and X = SCN (5)) in order to understand the potential influence of the halide and pseudohalide bridging ligands on the physical properties and their electrical response to vapors of these materials. The structural characterization of the series shows a common feature, the presence of -X-Cu(ANP)-X- (X = Cl, Br, I, SCN) double chain structure. Complex [Cu(ANP)(CN)]n (4) presents a helical single chain. Additionally, the chains show supramolecular interlinked interactions via hydrogen bonding giving rise to the formation of extended networks. Their luminescent and electrical properties have been studied. The results obtained have been correlated with structural changes. Furthermore, the experimental and theoretical results have been compared using the density functional theory (DFT). The electrical response of the materials has been evaluated in the presence of vapors of diethyl ether, dimethyl methylphosphonate (DMMP), CH2Cl2, HAcO, MeOH, and EtOH, to build up simple prototype devices for gas detectors. Selectivity toward gases consisting of molecules with H-bonding donor or acceptor groups is clearly observed. This selective molecular recognition is likely due to the 2-amino-5-nitropyridine terminal ligand.

mcSi and CdTe solar photovoltaic challenges: Pathways to progress

Multi-crystalline Si (mcSi) and CdTe solar photovoltaic technologies have gained significant improvement. Shockley?Queisser (S?Q) limit consideration further progress of open-circuit voltage (Voc), fill factor (FF) and the efficiency of CdTe cell are anticipated. Sub-bandgap parasitic absorption, grain boundaries and back contacts recombination lessening are vital to minimize these opto-electrical losses. mcSi and CdTe heterojunction (HJ) cells? intrinsic thermal co-efficient to optical (bandgap) loss, interface and bulk defects and related thermal diffusion are possible opto-electrical limitations. Wafer based mcSi passivated emitter rear contact (PERC) and tunnel oxide passivated contact (TOPCon) over Al back surface field (Al-BSF) contact have incredibly progressed in current decades. Similar as mcSi cell, advancement of commercial CdTe cell is desired. Reviewing CdTe and mcSi/cSi (photo-physical similarity) based one hundred and fifty research papers it is comprehended that not only band aligned but also thin, transparent passivation window and electron reflector as barrier are central to minimize the shortcomings. CdTe absorber thickness-dependent Voc and fill factor trade-off while diverse window and barrier layer performance review are realized optical transparencies to electrical loss outcome. Stated opto-electrical development purpose thin absorber supportive band and lattice matching double HJ or graded CdSexTe1-x/CdTe HJ is possible realistic pathways. mcSi thin wafer is exposed to minimize bulk degradation that is caring for a stable and cost-effective PV. Finally, CdTe solar cells present limitations to laboratory design towards the best progression trails are focused. It is anticipated to limit the levelized cost of energy (LCOE).

DFT calculations of Cun Om0 / + clusters: Evidence for Cu2O building blocks

The structures of Cun Om+ / 0 and Cun Om Hl+ / 0 clusters are obtained by DFT calculations. Clusters with even and odd number of copper atoms can be, respectively represented as (Cu2 O)n+ and [(Cu2O)nCu]+. The latter are highly symmetrical and show positive charge uniformly distributed on the Cu atoms, whereas in the former, one of the Cu2O subunits exhibits a higher positive charge. It is found that the divalent oxygen of Cu2O is the reactive site involved in cluster growing. The structures of Cun Om H2+ / 0 and Cu2nOnH+/0, correspond, respectively to hydrated and hydrogenated clusters.
