Abstract
The effect of temperature and the cesium concentration in the external solution on the sorption capacity of titanium phosphate obtained upon the heterogeneous interaction of the (NH4)2TiO(SO4)2 · H2O crystalline salt with phosphoric acid is studied. Sorption on titanium phosphate is shown to be best described by the Langmuir isotherm. When describing the sorption kinetics of solutions, it is necessary to consider both the possibility of diffusion and adsorption limiting the process rate. The use of the chemical kinetic models shows that the stage of chemical interaction of metal ions with functional groups of the sorbent also contributes to the overall rate of the process.
