氯气和二氧化氯混合组分的分别测定

Separate Determination of Chlorine and Chlorine Dioxide in Mixture

氯气和二氧化氯气体共存时，用现有的分析方法不能分别测定。采用甲基橙比色法和硝酸银比浊法分别测定氯气和二氧化氯的总量，然后根据各自的反应原理和标准曲线方程建立二元一次方程组。通过求方程组的解，得到氯气和二氧化氯各自的含量。同时还研究了冷阱分离法，并对两种方法的测定结果进行了比较。

The total of chlorine and chlorine dioxide in mixture is determined by methylorange colorimetry and silver nitrate turbidimetry, and then upon the individual reaction principle and standard curve,coupled binary equation of frist degree is established. By solving the coupled equation, separate concentration of chlorine and chlorine dioxide is measured.At the same time, chlorine and chlorine dioxide are determinated by cold coil. The results of two method above are analysed and compared.
