摘要
文章阐述了采用重铬酸钾法和快速消解光度法测定COD的方法。要点是对试样事先测定氯离子质量浓度,再对试样预先进行银盐处理和排列分组,在测定过程同时加入掩蔽剂以消除氯离子的干扰。从测定结果看本公司酸洗处理后的废水为高氯低COD的废水,这一结果使文中论述的方法原理得到了验证。
The paper described a COD determination method using potassium dichromate method and Fast digestion-spectrophotometric method.The main point was to determine chloride ion mass concentration first,and then process the sample with silver halide,alignment and grouping the sample,meanwhile add masking agent in order to eliminate the influence of chloride ions.The determination results reflect that the pickling waste water becomes high chloride low COD wastewater after treatment.The results also corroborate the methods and principles described in the paper.
