Изобретение относится к способам выделения серебра (I) и может быть использовано в технологии извлечения серебра (I) из технологических и природных объектов. Предлагаемый способ отличается тем, что, с целью повышения эффективности сорбционного извлечения серебра (I), сорбцию ведут с помощью сорбента, представляющего собой сшитый полиорганилсил сесквиоксан - поли[S, S1-бис(3-силсесквиоксанилпропиламино) дисульфид]. Выделение серебра (I) осуществляется из растворов в широком интервале концентраций азотной кислоты 0,01 - 5М и тиосульфатных растворов. Предлагаемый способ характеризуется высокой избирательностью по отношению к серебру (I) в присутствии 103 - кратного количества суммы неблагородных металлов: железа (III), меди (II), цинка (II).The invention relates to methods for the separation of silver (I) and can be used in the technology of extracting silver (I) from technological and natural objects. The proposed method is characterized in that, in order to increase the efficiency of sorption extraction of silver (I), sorption is carried out using a sorbent, which is a crosslinked polyorganylsil sesquioxane - poly [S, S 1 -bis (3-silsesquioxanylpropylamino) disulfide]. Silver (I) is extracted from solutions in a wide range of nitric acid concentrations of 0.01-5 M and thiosulfate solutions. The proposed method is characterized by high selectivity with respect to silver (I) in the presence of 10 3 times the number of base metals: iron (III), copper (II), zinc (II).
