Decabromodiphenylether (DBDE) is a brominated flame retardant which belongs to the group of polybromodiphenylethers (PBDEs) often used as a fire resistant additive in various well known polymeric systems like polystyrene, poly(acrylonitrile-butadiene-styrene) (ABS), polypropylene, etc. This compound can be considered as a persistent organic pollutant and presents certain risks for the environment owing to the fact that it is bioaccumulable and not biodegradable. A detailed investigation, described here, was carried out on the effect of ultraviolet/visible radiation on DBDE in ABS with the aim to study the photolytic reactions of this molecule in the solid state, in order to improve the economic and ecological treatment of brominated plastic waste from waste electrical and electronic equipment (WEEE). This study presents new aspects of the photochemical degradation of DBDE/ABS systems in the solid state. The photodegradation of DBDE in ABS was followed by Fourier transform infrared spectroscopy (FTIR) as well as by thermogravimetrical analysis (TGA). Good agreement was obtained for the results of both analytical methods in terms of the overall photolysis of DBDE.

十溴二苯醚（DBDE）是一种溴化阻燃剂，属于多溴二苯醚（PBDEs）组，通常在各种众所周知的聚合物体系（例如聚苯乙烯，聚（丙烯腈-丁二烯-苯乙烯）（ABS），聚丙烯等）中用作耐火添加剂。由于该化合物具有生物蓄积性和不可生物降解性，因此可被视为持久性有机污染物，并且对环境构成某些风险。对紫外线/可见光辐射对ABS中DBDE的影响进行了详细的研究，目的是研究该分子在固态时的光解反应，以改善溴化塑料的经济和生态处理。废弃电子电气设备（WEEE）产生的废物。这项研究提出了固态DBDE / ABS系统光化学降解的新方面。DBDE在ABS中的光降解之后是傅立叶变换红外光谱（FTIR）以及热重分析（TGA）。就DBDE的整体光解而言，两种分析方法的结果均取得了很好的一致性。
