摘　　要：研究了采用催化快速法测定工业废水中化学耗氧量 ( COD)的含量。该方法检出限范围为 4 5～ 10 0 0 mg/ L ,COD含量与吸光度成线性关系 ,相对标准偏差为 2 .5 %。该方法适用于监测工业外排废水。The application of catalyst acceleration process to determine the COD content in industrial waste water is studied. The process has a measurement range of 45~1 000 mg/L and the COD content is linear with the light adsorption capacity with a relative standard deviation of 2.3%. Therefere, the process is suitable for monitoring the industrial waste water discharged to the environment.
