摘要: The effect of pH on the adsorption nickel (II), copper cobalt lead manganese and iron (III) from concentrated chloride solutions onto Dowex M-4195 is reported for first time. This chelating resin has an unusual ability to adsorb many these metals, most notably copper, even at very low pH. selectivity metals makes this particularly attractive detoxifying acidic generated during processing ores minerals. uptake behavior high-chloride concentrations differs somewhat that lower previously in literature. discussed terms chemistry bis(2-pyridylmethyl) amine (bispicolylamine) functional group.
