Abstract
The results of studies to determine the effectiveness of KU-2-8 cation extracting copper ions from water hardness ions in the presence of low concentrations of copper ions. It is shown that at concentration of copper from 1 to 30 mg/dm3 extraction of copper takes place in static conditions inefficiently both from distilled and from tap water irrespective of an ionite form. This indicator decreases at increase in volume of solution at the fixed ionite volume. Significant efficiency removal of copper ions in this cation achieved in dynamic conditions using resin in acid and salt form in the presence of ions in solution stiffness. It was established that the efficiency of desorption of copper ions hydrochloric acid solutions in static conditions was low. In dynamic conditions reached almost complete desorption of copper ions by solutions of hydrochloric acid.
