【摘要】 本文研究了痕量钒（V）催化溴酸钾氧化邻氨基苯酚形成黄色产物的指示反应及其动力学条件,建了催化光度法测定痕量钒（V）的新方法,灵敏度为7×10^-13g/ml,测定范围0～0.06μg/25ml,钒（V）。更多还原

【Abstract】 In this paper, we find that V（V）can catalyze the indicative reaction ofresulting a yellow product, in which o-Aminophend can be oxidized by pota-ssium bromate. The kinetics conditions of the reaction have also been stu-died. A new high-selectivity method of determining trace V （V） is7×10^-13g/ml, and the range of Vanadinm is 0～0.06μg/25ml.更多还原
