Abstract

A method is described for determination of trace lead in feed-grade dicalcium phosphate with the correlation coefficient r = 0.9987,and within the range of marking average recovery rate 98.45% ～ 100.75%. The sample is dissolved with hydrochloric acid solution,and its lead content is determined in a reaction system of HCl-K3Fe(CN)6-NaBH4 by hydride generation atomic absorption spectrometry.
