Abstract:Eutrophication is a global issue that threatens drinking water safety and even theentire ecological balance.The excessive discharge of phosphorus (mainly in phosphate)in water is one of the important reasons foreutrophication. Therefore,controling 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 this metal-based material that has not received enough atention.In 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 emerging methods such as electro assisted adsorption and plasma further enhance the ability of Mn-based materials to remove phosphates.The present article reviews the ffects and mechanisms of phosphate removal using diferent Mn-based materials,and evaluates the application prospect of phosphate removal using different Mn-based materials.Then,from the perspective of increasing pHpzc or enhancing electrostatic efects,several methods for enhancing phosphate removal in Mn-based materials are analyzedand summarized.Finally,based on theexisting research,the current shortcomings and future development directions are proposed in order to provide a reference for future research on phosphate removal using Mn-based materials.
