摘要
采用扩散法提取植物样中的氟,用离子色谱法检测氟的含量。经试验,样品加标回收率在94.7%～104.7%之间,样品质量分数为7.10μg/g时,RSD为1.41%。此法操作简单,准确度高,精密度好,是一种测量植物样中氟含量的有效方法。
The authors extracted fluorine in plants by the method of diffusion and detected the content of fluorine by ion chromatography. Through test, the recovery of standard addition for plant samples was between 94.7% - 104.7% , the RSD was 1.41% when sample content was 7.10μg/g. The method was characteristic of easy performance, high accuracy and fine precision, and was an effective method to test the content of fluorine in plants.
