Soil organic phosphate (OP) is an important fraction of phosphorus in the soil environment. Its reactions in interfaces of the environment affects transport, transformation, bioavailability and environmental behaviors of phosphorus. This paper is a review that summarizes (1) reaction characteristics of adsorption-desorption and dissolution-precipitation of typical OPs on the surface of soil minerals and their microscopic mechanisms, and (2) environmental impacts, i.e., effects of the interaction between OPs and soil minerals on the speciation of OPs, interfacial reactions of metal ions, and colloidal chemical stability and dissolution-transfomation of the minerals. Soil OPs generally contain multiple phosphate groups and have large relative molecular mass and high charge density. OPs could interact strongly with environmental minerals through interfacial reactions, which affects the charge properties of minerals, adsorption characteristics of co-existing metal ions, and colloidal chemical stability of minerals. Interfacial reactons of OPs and their mechanisms are affected by a number of factors, such as type and crystallinity of the mineral, relative molecular mass of OP, pH, temperature, and coexisting ions. Sorption density of OP on the surface of minerals generally decreases with increasing pH of the system, crystallinity of minerals, and relative molecular mass of OP. OPs may generally form inner-sphere complexes (hydrogen bonding interactions also plays a role in some cases) on the surfaces of minerals, and surface complexes can even transform to surface precipitates. The adsorption of OP and metal ions on mineral surface generally has certain synergistic effects, especially under low pH conditions, i.e., metal ions promote the adsorption of OP and vice versa; adsorption mechanisms vary with reaction system, including mainly formation of ternary surface complexes and surface precipitates, and in most cases simultaneously involve multiple ones. In the end of the paper, discussion is conducted on main research hotspots and directions for future researches related to interaction between OP and minerals in the environment.
