As highly toxic and carcinogenic substances, antimony and arsenic often coexist and cause compound pollution. Heavy metal pollution in water significantly threatens human health and the ecological environment. This article elaborates on the sources and hazards of compound antimony and arsenic contamination and systematically discusses the research progress of treatment technology to remove antimony and arsenic in water. Due to the advantages of simple operation, high removal efficiency, low economic cost, and renewable solid and sustainable utilization, adsorption technology for removing antimony and arsenic from sewage stand out among many treatment technologies. The adsorption performance of adsorbent materials is the key to removing antimony and arsenic in water. Therefore, this article focused on summarizing frontier adsorption materials' characteristics, adsorption mechanism, and performance, including MOFs, COFs, graphene, and biomass materials. Then, the research and application progress of antimony and arsenic removal by frontier materials were described. The adsorption effects of various frontier adsorption materials were objectively analyzed and comparatively evaluated. Finally, the characteristics, advantages, and disadvantages of various frontier adsorption materials in removing antimony and arsenic from water were summarized to provide ideas for improving and innovating adsorption materials for water pollution treatment.
作为高毒性和致癌物质,锑和砷经常共存并造成复合污染。水中的重金属污染严重威胁着人类健康和生态环境。本文详细阐述了复合锑砷污染的来源和危害,并系统地讨论了去除水中锑和砷的处理技术的研究进展。由于操作简单、去除效率高、经济成本低、固体制备可再生和可持续利用等优点,吸附技术在众多处理技术中脱颖而出。吸附剂材料的吸附性能是去除水中锑和砷的关键。因此,本文重点总结了前沿吸附材料的特点、吸附机制和性能,包括 MOFs、COFs、石墨烯和生物质材料。然后,描述了前沿材料去除锑和砷的研究和应用进展。客观分析和比较评价了各种前沿吸附材料的吸附效果。最后,总结了各种前沿吸附材料在去除水中锑和砷方面的特点、优点和缺点,为改进和创新水污染处理用吸附材料提供了思路。
