What is it about?
This research devoted to thiourea (T) and epichlorohydrin (ECH) based the ion exchangers and its sorption properties, the possibility of their analytical application. In this article, synthesized new selective ionites which is the based on epichlorohydrin, thiourea and melamine, to concentrate the silver metal, extraction it from Zn, and Cu.

Why is it important?
In this research work, the results of the study of the main properties of ionites, such as sorption exchange capacity for some metal ions (Cu2+, Co2+, Ag+), sorption indicators, thermal and chemical stability, the viscosity, are described. The degree of sorption of the obtained ions was determined by potentiometric titration. In order to evaluate the efficiency of ionite synthesized, its sorption properties were compared with the analogous properties of other ionites According to the result of the experiments, the sorption rate of ionites in a weakly acidic environment is higher than in other environments.
Perspectives
Writing this article was a great pleasure as it has co-author with whom I have had long standing collaborations. In this research work, we applied the separation and concentration of precious metals from local ores with ionites synthesized using local raw materials.

Currently, ionites are important for the separation and concentration of noble metals. The growth of population caused a sharp increase in the demand for noble and rare metals. It caused to we are need to recover them from secondary raw materials.
