| 摘 要： | 针对国标重铬酸钾法测定高氯离子含盐废水CODCr时的不足 ,采用密封消解法来测定高盐废水CODCr,通过丁酮氧化率、氯离子干扰、混配水样和实际水样测定结果的比较 ,对国标法和密封消解法进行了验证。试验结果表明 :在测定高氯离子含盐废水CODCr值时 ,密封消解法优于重铬酸钾法 ,能够真实准确地反映废水的CODCr。

| Abstract: | A sealed resolution method is used to determined COD Cr of salt bearing wastewater of high chlorides according to the shortage of the determination of it by potassium dichromate method in a national standard.The national standard method and sealed resolution method are verified by comparison of the test results of butanone oxidation rate,chloride interference,mixed water sample and the actual one.The results show that the sealed resolution method is superior to potassium dichromate method,which can reflect precisely COD Cr of the wastewater. |
