Significant efforts have been made to remove excess nutrient phosphorus in the form of aqueous phosphate ions from various wastewater streams to mitigate adverse environmental consequences to the watershed, such as eutrophication. Adsorption has long been a low-cost and highly effective method of phosphate removal which chiefly relied on immobilizing this valuable nutrient in low solubility solids. Magnesium-based adsorbents are emerging as an economically feasible solution to the phosphate removal problem that have the added benefit of facilitating nutrient recycling via the production of slow-release fertilizer. The current scientific literature on Mg-based adsorbents for phosphate has focused on a diverse range of techniques for the resulting material characterization, adsorption equilibrium and the observed kinetics making direct comparison between the diverse Mg-based adsorbents difficult. This tutorial review aims (a) to provide an overview of the state of the art in Mg-based phosphate adsorbents and (b) to propose a generalized data interpretation roadmap necessary to bridge the gap between the observed fundamental kinetics and mechanistic insights reported in the literature.

磷酸盐在含Mg的材料上的吸附综述：动力学，平衡和力学见解

为了从各种废水流中去除磷酸根离子形式的过量营养磷做出了巨大的努力，以减轻对流域的不利环境影响，例如富营养化。长期以来，吸附一直是一种低成本，高效的除磷方法，其主要依靠将这种宝贵的营养物固定在低溶解度的固体中。镁系吸附剂正在成为一种经济上可行的解决方案，以具有促进营养循环的附加益处的除磷问题通过生产缓释肥料。当前关于磷酸盐的基于Mg的吸附剂的科学文献集中在用于所得材料表征，吸附平衡和观察到的动力学的多种技术，这使得难以在各种基于Mg的吸附剂之间进行直接比较。本教程审查旨在（a）提供基于Mg的磷酸盐吸附剂的最新技术概述，以及（b）提出弥合在观测到的基本动力学和机理见解之间的差距所必需的通用数据解释路线图。文学。
