摘要
水污染及其修复已成为全球性的不断升级的问题,特别是湖泊和河流中存在的重金属污染问题。如何去除其中的重金属也引发了很多的讨论。与活性炭、低成本工业废料、聚合物、矿物和金属纳米颗粒相比,金属诱导的生物吸附剂可能是更有希望的选择。磁性生物吸附剂可以促进比表面积、孔径和表面功能的发展,从而提高吸附能力并促进生物吸附剂的回收。本文介绍了磁性生物吸附剂的不同合成方法,比较了它们的优缺点。
Water pollution and its remediation have become a global problem,especially heavy metals pollution of lakes and rivers.How to remove heavy metals from them has also caused a lot of discussion.Compared with activated carbon,low-cost industrial waste,polymers,minerals and metal nanoparticles,metal-induced biosorbents may be a more promising option.Metal nanoparticles show high efficiency in removing trace contaminants.Magnetic biosorbent can promote the specific surface area,pore size and surface function,thereby improving the adsorption capacity and promoting the recovery of biosorbent.In this paper,the different synthesis methods of magnetic biosorbents were introduced,and their advantages and disadvantages were compared.
