The production and consumption of antibiotics are huge in China.Moreover,the pollution of residual antibiotics in envi-ronment is serious because the remediation level of antibiotics is low.Due to its high chemical reactivity,nano zero-valent iron(nZ-VI)can remove many kinds of contaminants.The review summarized the sources,transformation,damages of antibiotics,as well as the chemical preparation and physicochemical modification of nZVI.The application and mechanisms of nZVI for antibiotics removal was also introduced in the review.At last,the development directions and the defects in remediation of antibiotics by nZVI were summarized.%我国是抗生素生产和消费大国,污染严重,对环境中残留抗生素整体治理水平较低.零价纳米铁具有良好的化学反应活性,能有效地去除环境中污染物.本文详细介绍了抗生素的来源、迁移路径、生态危害及零价纳米铁的化学制备方法和物理化学改性等.同时,对零价纳米铁去除抗生素的应用进展及去除机理进行了详细论述,并对其发展方向和存在不足进行了总结.
