Abstract

A new method of determining the concentration of lead ions.This methods makes up the limitation which the common ways (e.g.dithizone colorimetry and atomic absorption spectrophotometry)have if virudent poison KCN is used, the standard curve is protracted, the operation process is too complicated, and is only suitable for the determination of matter with low concentration.The operation process of the new method is simple and the determination result is accurate (the relative error is 0.01 %and the relative standard deflectivity is 0.41 %).It is suitable for the determination of lead with high concentration.
