低成本吸附材料去除水和废水中药物的研究进展

Research Progress of Removal of Drugs from Water and Wastewater with Low-cost Adsorbents

药物会对人类健康和生态环境造成潜在威胁,已成为自然环境中的一种新型污染物,因而受到广泛关注。本文简述了药物在环境中的主要来源和危害,以及去除水环境中药物污染的重要手段——吸附法。早期的商业活性炭作为药物吸附剂得到了广泛的研究,但其较高的成本限制了其大规模的应用。笔者从几种低成本吸附剂用于吸附水和废水中的药物的应用研究出发,对药物的来源、环境和潜在的风险以及处理办法,吸附技术研究以及低成本材料在药物吸附去除方面的应用进展等内容进行综述,并对水和废水中药物吸附的前景进行了展望。

Pharmaceuticals was become a new pollutant in the natural environment, which may threaten to human health and ecological environment and was received more and more attention. In this paper, the main source and harm of drugs in the environment and the important method to remove pharmaceuticals in water environment——adsorption method were introduced.Early commercial activated carbon was widely studied as adsorption materials, but its high cost limited its large-scale application.Based on the research and application of several low-cost adsorbents in the adsorption of pharmaceuticals in water and wastewater,the author introduced the sources, environment, potential risks and treatment methods of pharmaceuticals, the research technology of adsorption and the application progress of low-cost materials in pharmaceuticals removal were introduced, and the research trend of pharmaceuticals absorption from water and wastewater was prospected.
