摘　　要：本文介绍了一种快速测定高氯废水中ＣＯＤＣｒ的方法。提出以ＡｇＮＯ３和ＣｒＫ（ＳＯ４）２·１２Ｈ２Ｏ代替ＨｇＳＯ４作为消除氯离子干扰的抑制剂。试验结果表明，它能有效地抑制水样中高达２５０００ｍｇ／Ｌ氯离子的干扰。本法具有较高的准确度和精密度。A rapid method has been presented for the determination of COD in wastewater samples containing high level Cl -.This method proposed the use of AgNO 3 and CrK(SO 4) 2·12H 2O instead of HgSO 4 to suppress chloride interference.The results of the tests show that the chloride interference is effectively suppressed up to chloride levels of approximately 25000 mg/L.This method is of higher accuracy and precision.
