影响水质高锰酸盐指数结果准确性的因素

Factors influencing the accuracy of water quality permanganate index results

水质高锰酸盐指数是指在处于一定条件下,氧化剂为高锰酸钾,能够用于氧化水中无机物,有机物等一些还原性物质,所消耗的氧含量,单位为mg/L。利用高锰酸盐指数能够反映地下水、地表水及生活饮用水中有机污染程度。但在日常水体监测中,检测难度系数是比较高的。为了提高高锰酸指数分析结果的准确性,需要在分析过程中确保各分析环节的准确度,避免对高锰酸盐指数分析结果产生影响。本文研究中针对在分析水质高锰酸盐指数时影响因素开展深入分析。

Water quality permanganate index refers to the oxygen content consumed by potassium permanganate as the oxidizer under certain conditions,which can be used to oxidize inorganic and organic substances in water and other reducing substances,in milligrams per liter.The permanganate index can reflect the degree of organic pollution in groundwater,surface water and drinking water.But in daily water body monitoring,the detection difficulty coefficient is relatively high.In order to improve the accuracy of the permanganate index analysis results,it is necessary to ensure the accuracy of each analysis link in the analysis process to avoid affecting the permanganate index analysis results.In this study,an in-depth analysis of the factors affecting water quality permanganate index is carried out.
