| 摘 要： | 为控制分析化学实验废液中有害离子含量，本文从降低反应物浓度入手，对高锰酸钾，重铬酸钾，碘量法，酸碱滴定等方法进行了研究。实验表明，降低反应物浓度不影响分析结果准确度，终点现象明显。

| Abstract: | To control the content of the poisonous ion in the analytical chemistry experiment, in this paper, the study about the method of potassium permanganate, potassium dichromate, iodine measure and acid-basic titration was done, which was started with the reactant content reduced. The result indicted that the reactant content reduced did not affect the exact extent of the analysis, and the phenomena was very distinctness in the end point. |
