Improvement of adsorption-ion-exchange processes for waste and mine water purification

Abstract

The increase of ecological safety level of the hydrosphere as a result of the improvement of the adsorption processes for waste and mine water purification by using natural sorbents and desalting processes via electrodialysis has been investigated. The optimal parameters of improved sorption processes with natural sorbents have been established. The mechanism of diffusion was studied by the “kinetic memory” method. Effective coefficients of pore diffusion were determined during sorption of pollutants by natural sorbents. The optimal parameters of electrodialysis with intermembrane filling by ion exchangers for demineralization of waste and mine water have been established.
