动力学XRFA法测定合金及矿中的微量钒
DETERMINATION OF THE TRACE VANADIUM IN THE ALLOY AND ORE BY DYNAMIC XRFA METHOD
-
摘要: 基于V5+对Fe2+诱导K2Cr2O7氧化Sb3+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。Abstract: Based on the fact that the K2Cr2O7 can oxidize Sb3+ by Fe2+ inducing,the oxidation reaction is inhibited by V5+,The method of vanadium determination by dynamic XRFA is established. The detection limit is 0.05μg/50ml and the determination range of vanadim is 0.05~2.6μg/50ml.
