摘要
化学化工等行业产生大量含无机盐的高浓度难降解有机废水,介绍了氯离子浓度和有机物浓度都大大超过测定范围的有机废水COD的测定方法。该方法当氯离子的浓度在20000~60000mg/L时,相对误差在0.15%~5.8%之间;并有较高的精密度,6次平行测定的结果相对标准差<2%;加标回收率为99%~101%;与标准方法相比不存在显著性差异。
Incineration is an ideal method for high salinity organic liquid wastes.Determination of COD in these organic waste liquids is dominant for design of burmer and estimation of incineration efficiency.It is presented high-speed catalytic method for oganic liquid with high concentration of chloride ion and organic compounds.Relative error is 0.15%~5.8% when the concentration of Cl-is 20 000 ~ 60 000 mg/L.Accuracy of the method is good,the relative error of six measured results is less than 2% and the recovery is 98%~102%.There is no “prominent difference” between standard method and high-speed catalytic method.
