新兴环境污染物三氯卡班研究进展

Research Progress of Emerging Environmental Pollutant Triclocarban

目前个人护理、医疗保健和工业运营等人类活动离不开化学制剂的使用,多氯芳香族化合物由于抗菌作用被广泛投入生产和使用,对环境、野生动物和人类产生干扰。三氯卡班是一种常见的抗菌添加剂,相关文献证明其对生物生长、生殖和代谢具有抑制作用。近年来新兴有机污染物三氯卡班引起了监管机构和研究人员的兴趣,也越来越多地关注到对三氯卡班的去除工艺。为此,重点综述了三氯卡班在环境和生物中的积累以及针对三氯卡班污染问题的治理方式,其中包括氧化降解、光催化、纳米剂吸附、滤膜和反渗透技术以及生物降解的不同方式。基于降解方式存在的二次污染,去除效率低等缺点,提出了多元化技术发展,多项技术联合作业,深度转化技术研究,改善降解材料,推广与应用等策略,为新兴环境污染物的去除提供新的思路和建议。

At present,human activities such as personal care,healthcare,and industrial operations cannot do without the use of chemical agents.Polychlorinated aromatic compounds are widely used and produced due to their antibacterial effects,causing interference to the environment,wildlife,and humans.Triclocarban is a common antibacterial additive,and related literature has proved that it has inhibitory effects on biological growth,reproduction and metabolism.Therefore,in recent years,the emerging organic pollutant triclocarban has aroused the interest of regulators and researchers,and more and more attention has been paid to the removal process of triclocarban.This paper focuses on the accumulation of triclocarban in the environment and biology,and the treatment methods for triclocarban pollution,including oxidative degradation,photocatalysis,nano agent adsorption,filter membrane and reverse osmosis technology,as well as different ways of biodegradation.Based on the shortcomings of secondary pollution and low removal efficiency in degradation methods,strategies such as diversified technology development,joint operation of multiple technologies,deep conversion technology research,improvement of degradation materials,promotion and application have been proposed,providing new ideas and suggestions for the removal of emerging environmental pollutants.
