流动注射-光度法测定磷

Determination of phosphorus by photometry combined with flow injection

采用流动注射技术测定了钢铁中磷。研究了催化剂、酸度诸因素对反应体系的影响,选定最佳条件,用于样品测定中取得了较好效果。采样频率为90次/h。

A method for the determination of phosphorus in cast iron and steel by using flow injection-photometry was described in this paper. The effects of catalyst and acidness and so on were studiedThe proposed method has been applied to determine phosphorus content in the cast iron and steel with satisfactory results
