摘要
探讨了化学需氧量(CODCr)热消解快速测定法的测试条件。建立的方法通过对雨水、生活污水和工业废水的化学需氧量(CODCr)测试考察,有95%的把握认为本方法的测试结果与国标法的结果无显著差异,即二者的测试结果吻合、一致。建立方法测试的精密度达到国标法的要求,消解时间从原来的2 h缩短到10 min左右,能够省时、准确、快速地分析,提高了工作效率,同时节约能源。
The test conditions of rapid determination of Chemical Oxygen Demand （CODcr） were discussed. Through the exploration of the rain, sewage and industrial wastewater cod （CODcr） tested, 95% confidence showed there were no significant difference of this method test results and the national standard method that was consistent. The test precision reached the national standard method request, digestion time shortened from the original 2 h to 10 min or so, which can be accurate, fast analysis, saved time, improved work efficiency, and saved energy.
