盐酸中氯离子对氟离子测定结果的影响

为了提高分析检测的效率,节约分析成本,减少对环境的污染.利用氟离子计检测的灵敏性、准确性、快捷和方便,通过是否除去盐酸中氯离子的来检测氟离子的方法,对含有已知不同浓度氟离子的盐酸溶液通过处理进行测量对比.结论:是否去除盐酸中的氯离子对测量其中含有的氟离子结果无多大影响,且无需去除氯离子,分析方法操作方法简便,节省时间,对环境污染小.

In order to improve the efficiency of analysis and detection,save analysis costs and reduce environmental pollution.The sensitivity,accuracy,speed and convenience of the detection by the fluoride ion meter are measured by comparing whether or not the fluoride ion in the hydrochloric acid is removed to detect the fluoride ion,and the hydrochloric acid solution containing the known different concentration of the fluoride ion is processed and compared.Conclusion:Whether to remove the chloride ion in hydrochloric acid has little effect on the measurement of the fluoride ion contained in it,and there is no need to remove the chloride ion.The analytical method is simple,saves time and has little environmental pollution.
