A system for separation of zinc traces from large amounts of cadmium is proposed in this paper. It is based on the solid-phase extraction of the zinc in the form of thiocyanate complexes by the polyurethane foam. The following parameters were studied: effect of pH and of the thiocyanate concentration on the zinc extraction, shaking time required for quantitative extraction, amount of PU foam ne...

Selenium enriched nickel selenide (NiSe-Se) nanotubes supported on highly conductive foam (NiSe-Se@Ni foam) were synthesized using chemical bath deposition with the aid of lithium chloride as a shape directing agent. The uniformly grown NiSe-Se@Ni foam, its large number electroactive sites, facilitated rapid diffusion and charge transport. electrode, exhibited superior specific capacitance valu...

This report describes the experimental and modeling work performed to evaluate porous cathodes for the electrochemical reduction of nitrates and nitrites in liquid wastes. The experiments were done using the MPt cell with two different porous cathodes: nickel foam and TySARm SBS. The experimental results are compared with each other and to those obtained with a planar nickel cathode. The result...
