摘要
本文对ICP AES法测定氨甲环酸中痕量Pt和Ba的方法进行了研究 ,着重对氨甲环酸试样的不同分解方法进行了比较 ,用酸直接分解试样 ,方法简便、快速 ,试剂空白低 ,方法的回收率大于 96 2 % ,相对标准偏差小于 5 % ,准确度及精密度均符合要求 ,可用于氨甲环酸的生产控制和成品的检验分析。
The method of ICP-AES to determine trace Pt and Ba in tranexamic acid is proposed in this paper. The decomposition method of tranexamic acid has been studied, and sample decomposed with acid directly is adopted. The method is simple and rapid, the blank of test sample is low. The recovery of method is higher than 96.2%, the relative standard deviation is less than 5%. The accuracy and precision of the method are satisfactory, it has been applied to the production control of tranexamic acid and analysis of finished products successfully.
