摘要
高盐废水的COD测定至今仍很困难,在此提出的氯化物校正法可消除CL^-离子干扰,减少HgSO_4量,获得准确的COD测定结果。此法尤其适用于Cl^-含量大于5,000mg/l的废水COD测定。
It is very difficult to determine COD in high saline wastwater up to now. The proposed method for chloride correction can eliminate the interference of the Cl^- ions,decrease the HgSO_4 and obtain the accurate results in determining COD. The method is appropriate especially to the determination of COD in wastewater whose the Cl^- concentration is more than 5,000mg/l.
