Chemisorption of phosphate ions and destruction of organomineral sorbents in acid soils

摘要

The chemisorption mechanisms of phosphate anions by iron (aluminum) containing sorbents in a soil under high phosphate loads were studied. The role of the metal-phosphate anions in the destruction of the sorbents was discussed. It was shown that the chemisorption of phosphate anions and the destruction of phosphated organomineral sorbents are interrelated processes. A significant part of the chemisorbed phosphates in association with sorbent metals and carbon passes into the liquid phase of soil systems.
