| 摘 要： | 建立了离子色谱-柱切换测定土壤浸出液中氟离子的方法。使用柱切换技术,将样品通过高聚物反相色谱柱进行在线预处理,分离氟离子和小分子有机酸,同时除去水溶性有机杂质,采用收集环收集氟离子并进入分析系统分析,消除了测定氟离子时普遍存在的干扰问题。分析系统的淋洗液为KOH溶液,流速为1.0 mL/min,采用抑制性电导检测,外标法定量。氟离子的线性范围为0.05~10.0 mg/L,相关系数为0.9999,加标回收率为103.4%~105.3%,相对标准偏差为2.0%~2.1%,检出限 (S/N=3)为5.50 μg/L。该方法适用于测定复杂基体样品中的氟离子。

| Abstract: | A new method was proposed for the determination of fluoride in soil water extract by ion chromatography with column-switching technique. A reversed-phase column was used as a pretreatment column on-line to separate fluoride and organic acids as well as to eliminate organics. Fluoride was collected by a collection loop and delivered to the analytical system. Under the optimum conditions, the linear range of the method for fluoride was 0.05-10.0 mg/L (r=0.9999), and the limit of detection (S/N=3) was 5.50 μg/L. The recovery was in the range of 103.4%-105.3% with the relative standard deviation of 2.0%-2.1%. The method could be applied to determine fluoride in complicated samples. |
