title: [Determination of trace platinum and barium in tranexamic acid by ICP-AES].
abstract: 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.
