摘要
介绍了氟化钠—氯化亚锡直接光度法测定不锈钢中磷的方法,所生成络合物其λ_(max)=720nm,磷量在0～45ug/mL范围内符合比耳定律,所拟定的改进方法用于测定不锈钢中的磷,结果令人满意。
Phosphorus in stainless steel was determined by molybdenum blue reduced spectrophotometric using NaF-SnCl2 in this paper. It was found that λmx of formed complex was at 720 nm. Beer's law is obeyed in the range of 0～45 μg/mL for phosphorus.
