三氯生的生物毒性及零价铁技术去除三氯生的研究进展

Research Progress on Toxicity of Triclosan and Removal Technology of Triclosan in Water Environment by Zero-valent Iron

三氯生是一种广谱抗菌剂,其生物毒性包括急性毒性、内分泌干扰效应和遗传毒性。零价铁因无毒、含量丰富、价格低廉、强还原性优点而被用于水中三氯生的去除。综述了不同零价铁材料去除三氯生的影响因素和降解机理。此外,鉴于零价铁去除三氯生的局限性,提出零价铁耦合微生物工艺强化三氯生去除效果。最后归纳了零价铁材料用于水中三氯生去除存在的问题,对零价铁耦合微生物技术未来发展前景进行了展望。

As a broad spectrum antimicrobial agent,the biotoxicity of triclosan including acute toxicity,endocrine disrupting effects and genetic toxicity was introduced.Zero-valent iron(ZVI)was used for the removal of triclosan due to its non-toxicity,abundance,low cost and strong reducibility.In this review,the influence factors and degradation mechanism of triclosan by different zero-valent iron materials were summarized.Moreover,considering the limitations of removing triclosan by zero-valent iron,zero-valent iron-microorganism coupling system was proposed to enhance the removal of triclosan.Finally,the problems of the removal of triclosan in water environment by zero-valent iron was summarized,and the future development prospects of zero-valent iron-microorganism coupling system were explored.
