摘　　要：高锰酸盐指数是反映水体中有机及无机可氧化物质污染的常用指标。根据高锰酸盐指数测定的分析原理,结合高原地区的沸点情况,对样品测定的加热时间进行改进优化。当延长加热时间至35 min(水浴沸腾,开始计时),标准样品测定结果接近真值。因此对原有方法进行了改良,提高了样品的检测效率,具有较高的准确度,可用于实际分析工作中。The permanganate index is a commonly used indicator to reflect the pollution of organic and inorganic oxidizable substances in water bodies.This article improves and optimizes the heating time for sample determination based on the analysis principle of permanganate index and the boiling point in plateau areas.When the heating time is extended to 35 minutes(start timing when water bath boils),the measurement results of the standard sample are close to the true value.The optimized method has improved the detection efficiency and accuracy,and can be used in practical analysis work.
