Resumen
The porous mixed oxide SiO2/TiO2/Sb2O 5 obtained by the sol-gel processing method presented a good ion exchange property and a high exchange capacity towards the Li+, Na+ and K+ ions. In the H+ M+ ion exchange process, the H+ / Na+ could be described as presenting an ideal character. The ion exchange equilibria of Li+ and K+ were quantitatively described with the help of the model of fixed tetradentate centers. The results of simulation evidence that for the H + / Li+ exchange the usual situation takes place: the affinity of the material to the Li+ ions is decreased with increasing the degree of ion exchange. On the contrary, for K+ the effects of positive cooperativity, that facilitate the H+ / K+ exchange, were revealed. 30 1 51 58 Clearfield, A., (1982) Inorganic Ion Exchange Materials, , CRC Press Inc.: Boca Raton, FL Vayssilov, G.N., (1997) Catal.
