汉钢煤气冷凝水中氯离子含量准确性测定技术研究

Research on the Accuracy Measurement Technology of Chloride Ion Content in Han Steel's gas Condensate Water

采用硝酸银滴定法测定煤气冷凝水氯离子实验中,由于被测溶液pH呈酸性,同时含有大量的铁离子,会对测定结果造成干扰。通过对煤气冷凝水进行处理,消除干扰离子,并采用加标回收法进行分析,最终准确测定煤气冷凝水中氯离子含量。

In the experiment of using silver nitrate titration to determine chloride ions in gas condensate,the pH of the measured solution is acidic and contains a large amount of iron ions,which can interfere with the measurement results.By treating the gas condensate,eliminating interfering ions,and using the spiked recovery method for analysis,the chloride ion content in the gas condensate is accurately determined.
