摘要
作为水体等污染程度的重要评价指标,化学需氧量的测定一直以来都是水体监测过程中相当重要的参数之一。本文重点就常见的化学需氧量测定方法 --国标法、库伦滴定法以及快速消解分光光度法及其测定过程中的质量控制要点进行了探讨。
As an important indicator of water pollution degree evaluation, COD determination has been a very significant parameter of water monitoring process. In this paper, the quality control points in the determination process of common COD determination methods, such as GB, coulometry titration and rapid digestion spectrophotometry, were mainly discussed.
