[The inorganic sorbent Evirkhip for water decontamination].

Inorganic synthetic sorbent "Evirhip" is recommended for eliminating of contaminants from water with varying degree of pollution. Comparative evaluation was carried out of the activities of the synthetic sorbent, natural dispersive minerals and activated charcoals with their surfaces being variously modified, using a model of typical representatives of intestinal microorganisms (Shigella sonnei, poliomyelitis type II, Sabin strain, viruses). Under stationary conditions of interaction of 1% sorbent "Evirhip" with Shigella sonnei sterilizing effect begins to reveal itself within 60 minutes. Decrease in infectivity of poliovirus occurs by one logarithm of the original level during 30 minutes contact. The paper discusses changes of cationic composition of water as a result of treating it by the sorbent, and feasibility of practical application of the sorbent in processes removing etiological agents of the intestinal infections from drinking, natural and waste water.
