薄膜包衣剂中砷含量检测预处理方法的研究

摘要

Arsenic content in the film coating agent has been determined by taking a different preprocessing methods and means of detection. A complete set of digestion method has been obtained by analysising of the difference between the results. And a full set of determination of arsenic content in a set of thin-film coating agentsubstances has been established, which can be used for arsenic-limitted safety evaluation of such substances.%　　通过采取不同预处理方式和检测手段，对薄膜包衣剂中砷含量进行测定。对不同消解方法中产生的结果差异进行分析，确立了薄膜包衣剂类物质中砷含量测定的准确试验方法，完全可以用于进行此类物质的砷元素安全性评价。
