离子色谱法测定生活水体中氟氯离子方法的研究

Study on Determination of fluorine and chloride in living water by Ion Chromatography

基于离子色谱方法原理测定水体中氟氯离子的含量。本文主要对离子色谱仪的方法条件进行优化,获得最佳的测量条件,并对方法的线性、检出限、重复性、及回收率进行分析实验。曲线相关系数大于0.999,回收率范围氟离子:96%-106%;氯离子:95%-104%;相对标准偏差(RSD)≤2.8%;方法定量下限氟离子:0.012mg/L;氯离子:0.009mg/L,结果较为满意。

The determination of fluorine and chloride ions in water based on ion chromatography.The paper optimizes the method conditions of ion chromatograph to obtain the best measurement conditions,and the linearity,detection limit,repeatability and recovery of the method were analyzed.The curve correlation coefficient is greater than 0.999,recovery range F-:96%-106%;Cl-:95%-104%;relative standard deviation(RSD)≤2.8%;limit of quantification F-:0.012mg/L;Cl-:0.009mg/L.The results are satisfactory.
