摘要
实验研究了硅锰合金中磷的磷钒钼荧光度分析法,在0.24~1.54m o l.L-1的硝酸介质中,磷酸根离子可以和钒酸根离子以及钼酸根离子作用生成可溶性的黄色配合物(P2O5.V2O5.22M oO3.nH2O),在460nm波长处测量吸光度,40μg^1500μg/50mL的磷符合比尔定律,本法用于硅锰合金中的磷的测定快速、准确。
Experimentally studying phospherus-vanadium-molybdenum fluorescence in silicon-manganese allog in the nitric acid medium of 0. 24- 1. 54mol ·l^-1 , phosphoric acid ion react with vanadium acid ion and molybdic acid ion to produce yellow coordinate（P2O5 · V2O5 · 22MoO3 · nH2O）. After testing luminous amount at 460nm wavellength, the phosphorus of 40μg-1500μg/50ml accords with Beer＇s law. If this method is used in testing the phosphorus in silicon--manganese alloy, its test is speedily and accurately.
