摘　　要：开发出测定高氯化物废水COD的密封消解法,该法可排除高浓度氯离子的干扰。通过丁酮氧化率、氯离子干扰、混配水样和实际水样的测定,对密封消解法和重铬酸钾法进行了验证。试验结果表明:在测定高氯离子废水的COD时,密封消解法优于重铬酸钾法,能够真实、准确地测定废水的COD。A sealed digestion method for determining COD in wastewater with high content chloride has been developed,which can eliminate the interference of high content chlorine ion.It is better than the national standard method based on the comparison between the two methods in terms of oxidation rate of butanone,interference of chlorine ion,analysis of synthetic water sample and actual water sample.It can exactly determine COD in wastewater.
