摘要
Abstract
A method for determination of trace polymerization retarders(4-methoxyphenol and hydroquinone) in industrial used acrylonitrile has been developed by gas chromatography.The quantitative analysis was performed by gas chromatography-flame ionization detector with single point external standard method.The method was characterized by the recovery ranged from 97.6％ to 102.0％.The repeatability ranged from 0.29％-0.72％ for determination results;limit of detection ranged from 0.12,0.29 mg/kg.Compared with the spectrophotometric method,the established method was proved to be simple,fast and accurate,and protect the employee health through reducing the contact between them and acrylonitrile,which was suitable for the determination of polymerization retarders in industrial used acrylonitrile.关键词
