摘要
本文采用离子交换—比色法测定农业地质样品中的微量碘,本方法检出限为0.5×1-0 6,精密度达到2.4%。方法准确、快速、简便、成本低,适合大批量样品的测定。
An ion--exchange colorinmetry for determining micro--iodine in agricultural reconnaissance survey samples was studied. The detection limit of this method is 0. 5 ×10^-6, the precision comes to 2. 4％. The method has some characteristics with accuracy,fast, simple and low cost. It is suited to determine sample in batches.
