The purpose of this work was to study the process of adsorption of phosphate on natural and synthesized sorbents, such as aluminosilicates. The sorption properties of natural zeolite for phosphate under static and dynamic conditions were investigated. The zeolite on the basis of the coal fly ash of Dobrotvorskaya heat power plant was synthesized and modified. The equilibrium values of adsorption capacity were determined, and the corresponding isotherms were constructed at a temperature of 20° C. The kinetics of adsorption under mechanical mixing conditions was investigated. The limitation stages of the adsorption process was established. The speed, power and pressure diagrams of the apartheid were calculated and constructed.
