摘要
作为目前广泛使用的氯系阻燃剂,四氯双酚A(TCBPA)在运输、使用和处理的过程中会不可避免地释放到环境中,并通过各种途径进入人体,产生危害。简介了TCBPA的基本性质和制备,阐述了其环境分布及毒性,并总结了其降解技术的研究进展,最后对该领域未来的研究方向进行了展望。指出:应当进一步研究TCBPA微生物降解的机理和分子基础,并引入光催化、高级氧化等其他降解技术;同时,开发新型环境友好的阻燃剂不失为一种根源上的解决方式。
As the widely used chlorine flame retardant, tetrachlorobisphenol-A （TCBPA）is released into the environment and causes harm to human during the processes of transportation, using and treatment. The properties and preparation methods of TCBPA were introduced. The environment distribution and toxicity of it were stated. The research progresses on degradation of TCBPA were reviewed. The future developing trends in this research field were prospected. It was pointed that： The mechanism and molecular basis of microbial degradation of TCBPA should be further studied, and other degradation technologies such as photocatalysis and advanced oxidation should be introduced; The development of new environmental-friendly flame retardants is an essential solution.
