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.
本文提出了用电感耦合等离子体发射光谱法（ICP - AES）测定氨甲环酸中痕量铂和钡的方法。研究了氨甲环酸的分解方法，采用直接酸分解样品。该方法简单快速，测试样品空白低。方法回收率高于96.2%，相对标准偏差小于5%。该方法的准确度和精密度令人满意，已成功应用于氨甲环酸的生产控制和成品分析。
