Abstract

ZEOLITOS QUE CONTIENEN CATIONES MEZCLADOS SON CONVENIENTEMENTE PREPARADOS SATURANDO LOS ZEOLITOS CON EL CATION MENOS FUERTEMENTE RETENIDO, E INYECTANDO LUEGO LOS CATIONES MAS FUERTEMENTE RETENIDOS EN UN IMPULSO EN UNA SOLUCION DE SALMUERA RECIRCULANTE QUE CONTIENE EL CATION MENOS FUERTEMENTE RETENIDO. EL CATION MAS FUERTEMENTE RETENIDO SE INTERCAMBIA DE ESTA FORMA CON EL CATION MENOS FUERTEMENTE RETENIDO SOBRE LA SUPERFICIE DEL ZEOLITO, DESPUES DE LO CUAL SE PERMITE QUE LAS PARTICULAS SE EQUILIBREN, APROXIMANDOSE LA DISTRIBUCION DE LOS CATIONES DENTRO DE LAS PARTICULAS A UN VALOR DE EQUILIBRIO.
