摘要：
The authors have studied the sorption of silver on copper(II) and nickel(II) hexacyanoferrates(III). The choice of these compounds was guided by their stability in acid and oxidizing media. Sorption of silver from nitric acid solutions by redox ion-exchangers based on nickel(II) and copper(II) hexacyanoferrates(III) proceeds by the mechanism of heterogeneous ion-exchange reactions. Redox ion-exchangers are recommended as effective sorbents for extracting silver from nitric acid solutions, treatment of which is of practical significance.
