高锰酸盐指数测定中影响因素的探讨

摘要

通过对酸性法测定高锰酸盐指数全过程的分析,结果表明水样静置时间、水样浓度、水浴时间、反应温度等因素影响测定结果。文章总结了测定过程中需要注意的几个关键环节,确保获得准确数据。%Through the analysis of the whole process of determination of potassium permanganate index using acid method,this paper will show the impact of aside time of water sample,density of water sample,water bath time and reaction tempurature and so on,against the determination results.And this paper will summarize some key steps during the process of determination of potassium permanganate index,which need extra attention in order to get accurate results.
