Abstract

Search of the ion exchangers having selectivity is of great importance as ionic exchange took an important place among the main methods of division, concentration and purification of various mixes of substances [6]. Due to the rapid development of important industries, petrochemical, galvanic, electronics, electrical equipment, etc. in our republic, the requirement to many transitional metals increases. Natural reserves of a number of non-ferrous metals Ag, Ni, Co, Cu, Zn, Cd and Hg in crust are decreased. Their loss in liquid wastes of various industrial processes are inadmissible. However, their presence in natural reservoirs above extreme admissible concentration (maximum allowable concentration) on the one hand lead to losses as valuable elements, on the other hand they are dangerous to not only human life, but also flora cause, faunae of reservoirs [3]
