Abstract

The work is devoted to studying the adsorption of copper and nickel ions on natural and modified layered aluminosilicate -montmorillonite, as well as its determination of thermodynamic parameters. The adsorption process was investigated on model solutions of copper (II) and nickel (II) -ions of heavy nonferrous metals with high toxicity and abundance as natural pollution and industrial water.
A substantial increase in the sorption capacity of the native-aluminosilicate by modifying its surface. The contributions of energy and structural components of the adsorption process.
Received and investigated sorbents can be used for sewage treatment metallurgical and galvanic production from ions of heavy and non-ferrous metals.
