摘要
指出了通过2种实验结果对比证明,快速烘箱法测定COD比回流法测定COD试验时间少,精密度更好,节省试验空间,大量节省试剂使用量,节省大量电能,是一种较好的替代回流法的方法。
The experimental results showed that: compared with the traditional reflux quick oven method, determining COD by quick drying oven method took less test time and needed less experimental space, less reagent dosage and less electric energy but led to better precision.Therefore quick drying oven method was a better alternative than the traditional reflux quick oven method.
