| 摘 要： | 研究了当钼和钒共存时，利用催化动力学分析法连续测定钼和钡含量的方法，以硫脲作诱导剂同时兼作钒的掩蔽剂，首先测定钼，再以抗坏血酸作诱导剂产生第二次Ｌａｎｄｏｌｔ效应，测得钼和钒的合量，从而实现了用一个标准系列实现两种离子的连续测定。

| Abstract: | This paper present a method for continuous determination of Molybdenum (VI) and Vanadium(V) with catalytic and kinctic analysis.First,thiourea was used as the inductive agent for Mo(VI) and the masking agent for V(V),achieve the first Landolt process,and the amount of Mo(VI) was determined.Then,as soon as the first Landolt process ended,ascorbic acid was added to the reaction mixture rapidly to activate V(V) and achieve the second Landolt process,thus the total amount of Mo(VI) and V(V) was determined. |
