Abstract

The paper deals with the study of inorganic acid uptake on hydrogels of titanium, zirconium, and tin hydroxides prepared by the sol-gel method in the form of regular spherical particles. The aim of the work was the determination of the basic conditions for the preparation of inorganic ion exchangers by means of the conversion of the hydroxide gel. The results obtained prove that the exchange of hydroxide groups of the gel phase for the respective anions plays the decisive role in the uptake on zirconium hydroxide. With similar titanium and tin compounds, the main process affecting the uptake is the formation of adsorption compounds and the free diffusion of the electrolyte into the gel phase. The possibilities of the application of the sol-gel method for the preparation of inorganic sorbents are discussed.
