电化学分析法测定工业亚磷酸中氯离子的含量

Determination of chloride from industrial grade phosphorous acid by electrochemical method

在化工行业标准中一般采用氯化银目视比浊法测定工业亚磷酸中的微量氯离子,该法测定数据不连续、误差较大。本文主要研究用电化学分析法来测定微量氯离子,这种方法具有简便、有效、适合大批量产品的检测与分析等特点。

The standard of chemistry industry applied the visual colorimetry to detect the chloride from industrial grade phosphorous acid. The data obtained is not online by this method and the error often occurred. The present paper introduced the determination of chloride from industrial grade phosphorous acid by electrochemical method. The method were simple,rapid and accurate.
