摘要
研究了在流动注射体系中采用微型离子交换柱在线地除去试样中铁等高价金属离子,磷钼蓝分光光度法测定钢铁中微量磷。方法的测定范围为05～50μg/mL,进样频率为120样/h。采用本法测定钢铁中微量磷,结果令人满意。
Study on FIA-phosphomolybdate blue spectrophotometric determination of phosphorus in iron and steel, using micro ion exchange column on line withdrawal ferric ion. Beer's law is obeyed in the range of 0 5-5 0μg/mL, sampling frequency is 120/h. The method has been applied to determine the micro amounts of phosphorus in iron and steel with satisfactory results.
