Abstract
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%.
