摘要
氯离子在废水的化学需氧量(COD)测定中会干扰测定结果,对于高氯低COD水样的干扰尤为明显,因此在测定COD时必须预先处理水样中的氯离子。针对目前测定COD时几种常用的处理氯离子的方法,从去除原理、效果、优缺点以及适用范围等方面进行了分析比较,以供参考。
The result was disturbed by chloride ion in determination of COD in waste water,especially for high chlorine low COD water sample.therefore,chloride ion must be pre-treated.Based on several commonly used methods for treatment of chloride ion,the removal principle,effect,advantages,disadvantages and the application range were analyzed for reference.
