Iron phosphates have rich chemical structures with various morphologies and sizes. Since they are environment friendly with good biocompatibility, they have good performances in the fields of catalysis and battery electrode material rising in recent years, as well as in the traditional fields like agriculture and steel. They also have important applications in adsorption, separation and concentration due to their unique structural characteristics. In this paper, iron phosphates are classified based on their common characteristics such as structure, morphology and size, and their application in the past two decades is reviewed, with emphasis on their application in adsorption, separation and concentration of different species. Further, their application in adsorption, separation and concentration of heavy metals is prospected.

磷酸铁的结构，形态，尺寸及用途

磷酸铁具有各种形态和大小的丰富化学结构。由于它们对环境友好且具有良好的生物相容性，因此它们在近年来兴起的催化和电池电极材料领域以及传统领域（如农业和钢铁领域）中具有良好的性能。由于其独特的结构特征，它们在吸附，分离和浓缩中也具有重要的应用。本文根据磷酸铁的共同特征（如结构，形态和大小）对其进行分类，并对其在近二十年来的应用进行了综述，重点介绍了其在不同物种的吸附，分离和浓缩中的应用。此外，还展望了它们在重金属的吸附，分离和浓缩中的应用。
