氯离子选择电极在氯碱厂工业废水COD测定中的应用

Application of chloride ion selective electrode in COD meature of industrial wastewater from chlor-alkali plant

用氯离子选择电极测定氯离子浓度,通过绘制氯离子浓度-COD校准曲线,求出氯离子的COD,由废水COD值扣除氯离子的COD,即可求得废水中有机物的COD值。该方法测定含氯离子废水COD能反映出废水中有机物污染物情况,简单易行、可操作性强。

To meature the concentration of C1 by Chloride ion selective electrode and to obtain COD contents by the concentration of C1-COD calibrated curve, we subtracted COD contents from Chlor-alkali and can get COD contents in organic pollutant of wastewater.COD contents can reflect organic pollutant condition in industrial wastewater by the measurement method. This method is simple and measurable.
