ABSTRACT

The "Aerosil" preparation (on the silicon base) is an effective sorbent of cation surface-active substances (CSAS, cationic surfactants). Up to 83% of CSAS is adsorbed from water during 5−36 min, with their concentration equivalent to 30-100 maximum levels permitted in fishery. The CSAS desorption from the sorbent is significant (50−89%) in acid (pH = 5.4) and insignificant (2−13%) in weakly alkaline (pH = 7.6) medium. No pronounced adverse impact of "Aerosil" on biennial carp blood was detected.
