ICP-AES测定土壤样品中的V和Ba

Determination of V and Ba in Soil Samples by ICP-AES

本方法采用氢氟酸、盐酸、硝酸、高氯酸4种酸溶解样品,用电感耦合等离子体-原子发射光谱法(ICP-AES)测定土壤样品中的V和Ba,RSD均小于3%,对国家一级标样进行测定,测定结果准确,此方法简便,快速,准确度高。

V and Ba in soil samples were determined by ICP-AES with pretreatment of digestion by HF,HC1,HNO3 and HClO4,and the RSDs were all less than 3%. This method has been applied to determining fist class standard samples, and the results are in good agreement with the recommended value. The method is simple, rapid and accurate.
