Determination of Copper and Iron in Silver Cyanide Liquor by Flame Atomic Absorption Spectrophotometry

Zhou Yuan

Abstract

The concentration of copper and iron in silver cyanide liquor were determined by the method of flame atomic absorption spectrophotometry.By this method,there were no interference from the other coexistent elements.The relative standard deviation for Cu and Fe is 1.92%-2.63% and 3.13%_3.73%,respectively.The recovery rate for Cu and Fe is 96.8%-101.6% and 97.5%_101.1%,respectively.
