| Abstract: | The method of elimination of nitrite interference in the determination of COD Cr by sulfamic acid and ammonium sulfamate is studied in this article.The masking property of masking agents to nitrite is discussed and the relations of nitrite and the adding quantity of masking agents are also set up.The results demonstrate that the masking property of masking agents to nitrite is satisfied and the method has been successfully applied to analyzing wastewater samples. |
