摘要:

随着新型阻燃材料的广泛应用,水体中已检测到溴系阻燃剂的存在。溴系阻燃剂是一种通过物理或化学方法抑制聚合物燃烧的持久性有机污染物,在生产使用过程中可能会对环境造成污染,并通过食物链进入人体,作用于神经系统对人体健康产生严重影响。介绍了高级氧化技术的作用机理及特性以及其在去除溴系阻燃剂方面的应用研究进展,阐述了光化学氧化、臭氧氧化、过硫酸盐氧化、Fenton氧化和类Fenton氧化、超声降解、电化学氧化等高级氧化技术的去除机理和技术特征。综合对比了高级氧化组合工艺对溴系阻燃剂的去除效果,并以四溴双酚A为例,比较了同一条件下不同高级氧化去除技术的降解效果及优缺点,针对目前高级氧化技术存在的问题对今后的研究方向进行了展望。

Abstract:

With the wide application of new flame retardant materials,bromine flame retardants have been detected in water bodies. Brominated flame retardants are persistent organic pollutants that inhibit the combustion of polymers by physical or chemical methods. They may pollute the environment during production and use,and enter into human body through the food chain,acting on the nervous system and causing serious effects on human health. The advantages and application of advanced oxidation technology in the removal of brominated flame retardants were introduced. The removal mechanism and technical characteristics of advanced oxidation technology such as photochemical oxidation,ozone oxidation,persulfate oxidation,Fenton oxidation and Fenton-like oxidation,ultrasonic degradation and electrochemical oxidation were described. The removal effects of brominated flame retardant by advanced oxidation combined processes were comprehensively compared. Taking tetrabromobisphenol A as an example,the degradation effects,advantages and disadvantages of different advanced oxidation removal technologies under the same conditions were compared. In view of the existing problems of advanced oxidation technology,the future research direction was prospected.

Key words: advanced oxidation, brominated flame retardant, organic pollutants, removal mechanism, free radicals
