摘要

FIELD: water treatment. SUBSTANCE: sodium alkylbenzenesulfonates polluting natural and waste waters are removed being precipitated with zinc salts in the form of water-insoluble complex associates with imidazole or its derivatives. When concentration of sodium alkylbenzenesulfonates is between 2,5 and 10.0 g/l, degree of their removal attains 92-94%. EFFECT: increased water purification degree. 2 cl, 2 tbl
