摘要
随着现代工业的发展,重金属水污染已成为最重要的环境问题之一,重金属离子毒性强、难降解,在很大程度上对人类、水生动物和植物有害,破坏生态系统。吸附法低成本、去除效率高、可循环利用等优点使其成为废水处理的重要方法之一。生物质材料资源丰富、成本低、绿色环保,以其为新型吸附剂原料被广泛研究。基于此,该文以金属有机骨架、沸石、生物炭类为例,首先综述了生物质复合材料的制备及改性方法,总结了吸附剂的性能对金属离子吸附的影响,其次阐述其与金属离子之间的吸附机理,最后对生物质复合材料在水污染治理发展方面提出展望。
With the development of modern industry,heavy metal water pollution has become one of the most important environmental problems.Heavy metal ions are highly toxic and difficult to degrade,being harmful to humans,aquatic animals,and plants to a large extent and damaging ecosystems.The advantages of low cost,high removal efficiency and recyclability of the adsorption method make it one of the important methods of wastewater treatment.Biomass materials are rich in resources,low cost,green and environmentally friendly,and have been widely studied as new adsorbent raw materials.Based on this,taking metal-organic framework,zeolite and biochar biomass materials as examples,this paper first reviews the preparation and modification methods of biomass matrix composites and summarizes the influence of the properties of adsorbents on metal ion adsorption,secondly elaborates the adsorption mechanism between them and metal ions,and finally puts forward the prospect of biomass matrix composites in the development of water pollution control.
