    摘要:

    富营养化是一个全球性的问题,威胁着饮用水安全乃至整个生态平衡。水体中磷(以磷酸盐为主)的过量排放是引起富营养化的重要原因之一。因此,控制水体中磷的浓度,特别是磷酸盐浓度,具有重要的意义。锰基材料具有良好的磷酸盐去除潜力,但现有综述缺乏对其系统性的归纳,是一种没有得到重视金属基材料。事实上,锰基材料在磷酸盐去除领域的研究已经从单一的锰氧化物发展到混合金属氧化物和氢氧化物、金属-载体复合材料和层状双金属氢氧化物(LDHs)等。同时,电辅助吸附法、等离子体法等新兴方法的出现进一步强化了锰基材料去除磷酸盐的能力。文章综述了不同锰基材料去除磷酸盐的效果与机理,并对不同锰基材料去除磷酸盐的应用前景进行了评述。然后,从提高pHpzc或加强静电效应的角度,分析总结了强化锰基材料去除磷酸盐的几种方法。最后,根据现有的研究内容,提出了目前的不足之处以及未来的发展方向,以期为今后锰基材料去除磷酸盐的研究提供参考。

    Abstract:

    Eutrophication is a global issue that threatens drinking water safety and even the entire ecological balance. The excessive discharge of phosphorus (mainly in phosphate) in water is one of the important reasons for eutrophication. Therefore, controlling the concentration of phosphorus in water, especially phosphate concentration, is of great significance. Mn-based materials have good potential for phosphate removal, but existing reviews lack a systematic summary of them, making them a metal-based materials that have not received much attention. ln fact, research on Mn-based materials in the field of phosphate removal has evolved from single manganese oxides to mixed metal oxides and hydroxides, metal-support composite materials, and layered double hydroxides (LDHs). Meanwhile, the emergence of emerging methods such as electro assisted adsorption and plasma further enhances the ability of Mn-based materials to remove phosphates. The present article reviews the effects and mechanisms of phosphate removal using different Mn-based materials, and evaluates the application prospects of phosphate removal using different Mn-based materials. Then, from the perspective of increasing pHpzc or enhancing electrostatic effects, several methods for enhancing phosphate removal in Mn-based materials are analyzed and summarized. Finally, based on existing research, the current shortcomings and future development directions are proposed in order to provide reference for future research on phosphate removal using Mn-based materials.
