Abstract

This paper is about mineral-matrix technology of polluted water refinement using sorbents with high sorptive capacity made from modified during intensive hidrolysys process of clay soils. Regularities of consecutive acid-base clay material hydrolysis are formulated in this paper. The mechanism of clay mineral transformation processes is reviewed. The advantages of aluminum silicate sorbents with increased sorptive capacity against well known solid-phase sorbents are proved. It’s noted that in developed aluminum silicate sorbents an increased sorptive capacity is conditioned by a huge set of sorptive-active phases. It’s also noted, that processes of polluted liquid clearing with the help of hydrolyzed aluminum silicates is based not only on sorptive processes, but on the principle of man- artificially transformed aluminum silicate matrix regeneration. It’s shown that sorbents based on hydrolyzed clay soils application increases effectiveness of polluted water refinement.
