Abstract:A method for the determination of tin content in silver anode slime by potassium iodate titration is established in this paper. Through Filtering off copper by dissolving in nitric acid, replacing of antimony, bismuth, arsenic and other elements by iron powder reduction, the interference of the determination of copper, antimony, arsenic and other impurity elements in copper anode slime was eliminated. The recovery rate of the method was between 99.7% ~ 100.4%. The results of precision experiments showed that the relative standard deviation (RSD, n = 11) was less than 1.1%. The operation of this method is simple and can meet the needs of production.
