Abstract
1. Способ получения цинковых кронов осаждением включающий обработку водной суспензии соединения цинка раствором хромового ангидрида, отличающийся тем, что в качестве соединения цинка используют гидроксид цинка, который получают из твердого отхода производства анионита АВ-17-8, содержащего карбонат цинка. ! 2. Способ по п.1, отличающийся тем, что к твердому отходу добавляют раствор кислоты и получают раствор соли цинка, который затем очищают от нерастворимых примесей, а к очищенному раствору добавляют раствор щелочи и получают осадок гидроксида цинка, после чего осадок гидроксида цинка отделяют от жидкой фазы и промывают водой.1. A method of producing zinc crowns by precipitation comprising treating an aqueous suspension of a zinc compound with a solution of chromic anhydride, characterized in that zinc hydroxide is used as the zinc compound, which is obtained from solid waste from the production of anion exchange resin AB-17-8 containing zinc carbonate. ! 2. The method according to claim 1, characterized in that an acid solution is added to the solid waste and a zinc salt solution is obtained, which is then purified from insoluble impurities, and an alkali solution is added to the purified solution and a zinc hydroxide precipitate is obtained, after which the zinc hydroxide precipitate is separated from the liquid phase and washed with water.
