开发了一种HPLC-UV/MS方法，用于识别和定量来自电子电气设备废物（WESTERN）的消费后塑料中的阻燃剂。记录并解释了15种溴系和磷酸酯系阻燃剂的常压化学电离光谱。该方法被施加到检测阻燃剂添加剂的聚合物提取物从加压液体提取固体聚合物。此外，通过凝胶渗透色谱（GPC）的应用，开发了用于可溶性苯乙烯聚合物的筛选方法以分离阻燃级分。该馏分被转移到在线耦合的HPLC柱，并通过UV光谱法检测，这使得聚合物溶液中的溴化阻燃剂的可靠的定性和定量分析。(C)2004 Elsevier B. V.保留所有权利。
An HPLC-UV/MS method has been developed to identify and quantify flame retardants in post-consumer plastics from waste of electric and electronic equipment (WEEE). Atmospheric pressure chemical ionisation spectra of 15 brominated and phosphate-based flame retardants were recorded and interpreted. The method was applied to detect flame retardant additives in polymer extracts obtained from pressurised liquid extraction of solid polymers. In addition, a screening method was developed for soluble styrene polymers to isolate a flame retardant fraction through the application of gel permeation chromatography (GPC). This fraction was transferred to an online-coupled HPLC column and detected by UV spectroscopy, which allowed a reliable qualitative and quantitative analysis of brominated flame retardants in the polymer solutions.
