摘要
把热分解法与氧化还原滴定法相结合来对工业液氯中溴含量测定进行探索,文章主要内容包括样品的吸收、处理、分解和氧化还原滴定等技术的综合应用,成功地解决了工业液氯中溴含量的测定这一课题,填补了液氯中溴检测方法的空白。本检测方法的回收率为96.0%～101.2%,RSD为4.05%。该方法准确、快速、简便,完全能够满足液氯化工应用上对其中溴含量的测试需要。
This paper explores the determination of bromine content in industrial liquid chlorine by combining thermal decomposition and redox titration.The main contents of this paper include liquid chlorine sample absorption,treatment,decomposition of samples and redox titration comprehensive application.The determination of bromine content in industrial liquid chlorine has been successfully solved.the paper has been filled blank of testing of bromine in industrial liquid chlorine.The recovery rate of this method is96%~101.2%and RSD is4.05%.The method is accurate,rapid and simple,and can completely meet the needs of bromine content measurement in liquid chlorination process.
