Kinetic researches of sorption separation of phosphorus from phosphorus sludge with usage of sorbents on the basis of native silica-alumina clays in the low-temperature area are limited with adsorption processes and sublimation. Bentonites, vermiculites and refractory clays are chosen for carrying out researches. The high-quality sorbents resistant to work in an aqueous and aggressive environment are obtained on their basis. In practical conditions the kinetics process can be defined not only by the speed of actually chemical reaction of nucleation or internal diffusion, but also with other phenomena. When the most slow stage of chemical interaction in the mix solid – fluid – gas is recrystallization and adsorption that is characteristic for our researches, naturally change of sorption speed defines  kinetics of interaction system.
