摘要
热电厂化学车间的化学中和池排水具有高氯低COD废水特点,由于氟离子含量高,使得氟离子对COD测定产生强烈干扰,本文通过使用硝酸银对水样中氯离子进行沉淀的前处理方法,消除了COD测定中氯离子的干扰,为该水体中COD的准确测定提供方法依据。
The thermal power company chemical workshop neutralization pool drainage with high chlorine low COD wastewater characteristics,because of the high concentration of chloride ion,makes the strong interference of chloride ions on the determination of COD,in this paper,by using silver nitrate precipitation of chloride ion in water samples pretreatment method,eliminates the interference of chlorine ion in determination of COD,provide the basis for the the accurate determination of COD in water.
