| 摘 要： | 本文通过实验研究，提出用低铬法(0．0250mol/L)测定稀土废水中的CODCr，该方法测定结果和高铬法比较误差较小，准确度提高，并给出了低铬法测定稀土废水中CODCr时，HgSO4最佳使用量。

| Abstract: | Through the researches in laboratory with low chrome method of 0.025mol/L to determine the CODcr in the waste water, it showed that error was smaller and accuracy was higher compared with the high Chrome method. The optimal volume of HgSO 4 was finalized when low Chrome method to determine the CODcr of rare-earth wastewater was adopted. |
