摘要
酸性高锰酸钾法是目前针对不同水质中耗氧量测定的基础方法之一。测定耗氧量过程中满足水浴温度、加热时间、滴定温度、酸度等其他实验条件外,有研究对实验过程中的K值作出了探讨,但未明确指出具体的采用范围。分析不同水样应选取的最佳K值范围。
Acid potassium permanganate method is one of the basic methods for measuring oxygen consumption in different tyes of water.So far,in addition to meeting experimental conditions such as water bath temperature,heating time,titration temperature and acidity,some studies have discussed the K value in the experimental process,However,there is few of studies point out the specific scope of application.In this study,the authors discuss the K value range for different water samples.
