摘　　要：就碱性高锰酸钾法测定海水中的COD值波动大.重现性差,各实验室COD值互校难度大等问题,本文研究了影响此方法的常规分析过程中的各项误差来源及防范措施。通过实验以及几个实验室互校对这几项影响因素进行了论述和探讨。Due to great fluctuation, poor reappearance and difficult check on the basis of the method of alkalinity potassium permanganate determination of COD in sea water in laboratories, this paper investigates error sources and effective measures of removing error sources in the conventional analysis. The some influence factors are discussed and described.
