摘要
化学耗氧量是工业污水、生活污水、工业废水有机物污染的重要指标 ,是常规分析测试的主要项目。为提高工作效率 ,笔者将回流时间从 2h缩短至 0
Determination of the chemical oxygen demand is an important index of organic pollutant in industrial wastewater and dometic wastewater,also is a main obiect of routine determination.In order to improve efficiency,we cut down recirculation time from two hours to half an hour and have done comparative tests simmltaneously.
