摘要
优化了碘的离子色谱分离和测定条件,仅使用保护柱IonPacAG11柱,即可快速测定土壤中的碘。方法检测限0. 04μg/g(3倍的标准偏差),测定了8个国家一级标准物质中的痕量碘,验证方法可行性,并且结果与标准值相符,相对标准偏差(RSD)小于10% (n=12)。该方法适用于大批量化探样品中碘量的分析。
The chromatographic separation and measurement conditi on s of iodine are optimized. Rapid measurement of iodine in soil is thus achieved with protective column IonPacAG11. The detection limit of the method is up to 0. 04 μg/g (3 times of standard deviation). Trace iodine in 8 certified reference materials was measured with this method, which gives results in conformity with the standard values, with relative standard deviation (RSD) less than 10% (n =12). The method is proved feasible and applicable to measurement of iodine fo r large batches of geochemical samples.
