Abstract
FIELD: purification of drinking water. SUBSTANCE: method is carried out by precipitation of hexacyano ferrate of transition metal on the surface of porous carrier. Said precipitation takes place by consequent impregnation of said carrier by hot solutions of salts of transition metal, potassium hexacyano ferrate and zinc sulfate. Mixing and drying are carried out after each impregnation. EFFECT: improves efficiency of the method.

Использование: очистка питьевой воды от ионов радиоактивного цезия. Сущность: высокая химическая устойчивость сорбента по отношению к воде позволяет в процессе эксплуатации практически полностью исключить вымывание в воду токсичных гексацианоферрат ионов, имеет высокий ресурс по ионам Cs+. Это достигается осаждением гексацианоферрата переходного металла на поверхности пористого носителя путем последовательной пропитки его горячим раствором соли переходного металла, гексацианоферрата калия и сульфата цинка с перемешиванием и сушкой после каждой пропитки.Usage: purification of drinking water from radioactive cesium ions. Essence: the high chemical stability of the sorbent with respect to water allows during operation to almost completely eliminate the leaching of toxic hexacyanoferrate ions into water, and has a high resource for Cs + ions. This is achieved by precipitation of the transition metal hexacyanoferrate on the surface of the porous support by successively impregnating it with a hot solution of the transition metal salt, potassium hexacyanoferrate and zinc sulfate with stirring and drying after each impregnation.
