摘要
COD是污水处理的重要指标。文章以硫酸钛代替硫酸银,论证了方法的可行性,并考察了不同含量氯离子及不同消解温度对检测结果的影响。结果表明,以硫酸钛代替硫酸银后,减轻了氯离子对COD检测干扰,降低了消解温度。
COD is an important indicator of sewage treatment.This article uses titanium sulfate instead of silver sulfate,demonstrated the feasibility of the method,then investigated the influence of different content of chloride ion and different digestion temperature on the detection result.The results show that after the titanium sulfate instead of silver sulfate,reduce the interference of chloride ion on COD detection,and reduced digestion temperature.
