Determination of Zinc and Cadmium in Zinc Alloy

This article discussed the titration of the total content of Zinc and Cadmium in Zinc alloy by EDTA standard solution in the pH range of 5.5～6.0,and the respective calculations for Zinc and Cadmium with mathematic formulae.The method is simple and rapid,and shows accuracy and good precision.The relative standard deviation(RSD) is less than 0.8%.
