摘要
指出酸性高锰酸钾法测定化学需氧量是饮用水中COD测定的常用方法,就该测定的几种方法进行了对比试验和分析,结合工作经验,提出了一些操作建议,从而使得测定结果的相对误差减小。
It pointed out that Acid Kali Permanganate method was common method to measure chemical oxygen consumption （COD） in water. Several methods of measuring COD were compared and analyzed experimentally, combined with working experience, and some operating suggestions were proposed, so as to make measured result error reduce to minimum.
