Аннотация:A method of group extraction of As, Se, Te, and Cd using hydroxides of iron, lanthanum, and magnesium in analysis of technogenic raw materials which makes it possible to simplify determination of the listed elements and to consider and reduce possible interferences is proposed. On the basis of the performed studies, an ICP-AES express method of determination of toxic elements in technogenic copper-containing raw material is developed. The relative standard deviation of the results of analysis performed using the developed method is 9–2.5% at concentrations of the determined elements from n × 10−4 to n × 10−1 wt %.
