| 摘 要： | 介绍自动电位滴定法测定炼油工业污水中氯离子含量。炼油工业污水样品经加热煮沸、双氧水氧化等预处理后,通过调节使其pH=2～6,以硝酸银标准溶液为滴定剂,在自动电位滴定仪上进行电位滴定。试验表明,本方法可以用来测定带色度的炼油工业污水样品,且对样品的酸碱度无苛刻要求,过量的双氧水不影响测定结果,不同浓度的标准样品其测定结果与其标称浓度无显著性差异。

| Abstract: | A new method for the determination of chloride ion in oil refining industry sewage by automatic electrictitration method was recommended. The oil refining industry sewage pretreated by boiling and oxidation of hydrogen peroxide solution, adjusted its pH that ranged from 2 to 6,was titrated by silver nitrate standard solution with automatic potentionmetric titrator. The experimental results indicated that the content of chloride ion in coloured samples can be determined by this method and that superfluous hydrogen peroxide solution had no influence on the determination. This method had no rigorous limits of acidity. There were not notable diversity between the determination results and the standard value of the standard solutions with different chloride ion content. |
