| 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%- 00.75%. 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. |
