摘要
基于Ｖ￣（５＋）对Ｆｅ￣（２＋）诱导Ｋ＿２Ｃｒ＿２Ｏ＿７氧化Ｓｂ￣（３＋）反应的抑制作用，建立了动力学ＸＲＦＡ测定钒的方法，检测限为０．０５μｇ／５０ｍｌ，测定范围为０．０５～２．６μｇ／５０ｍｌ钒。
Based on the fact that the K_2Cr_2O_7 can oxidize Sb￣(3+) by Fe￣(2+) inducing,the oxidation reac-tion is inhibited by V￣(5+),The method of vanadium determination by dynamic XRFA is established. The detection linmt is 0. 05μg/50ml and the determination range of vanadinm is 0. 05～2.6μg/50ml.
