MODIFICACIÓN Y CARACTERIZACIÓN DE UNA VERMICULITA COLOMBIANA CON ESPECIES DE TITANIO, ZIRCONIO Y SULFATO/ MODIFICATION AND CHARACTERIZATION OF A COLOMBIAN VERMICULITE WITH TITANIUM, ZIRCONIUM AND SULFAT/ MODIFICAÇÃO E CARACTERIZAÇÃO DO VERMICULITE COLOMBIAN COM TITÂNIO, ZIRCONIÕ E SULFATO

Resumen en portugués O trabalho atual relata os resultados do produto químico, caracterização estrutural e textural de um vermiculite Colombian modificado com espécie simples do Zr e o Ti, e o sistema misturado do Ti-Zr no Zr/atômico nominal das relações (Ti + Zr) = 0.1 e 0.5. Adicionalmente, a incidência da presença do sulfato foi avaliada sobre o sulfato das relações/metal nominais 0; 0.25 e 0.35, incorporando sulfato já seja na solução ou do intercalação, ou pelo impregnaç (mas) ão em sólidos modificados e calcinados. Os resultados indicam que quando o sulfatação é realizado pelo intercalação, a natureza química da solução do intercalação afeta a quantidade de metal incorporado, dependendo do sulfato/metal usados na relação. Quando o sulfação impregnando é realizado, as propriedades texturaes, as estruturais e as morfologicas de sólidos obtidos fortemente estão afetadas e acompanhadas de uma fixation de enxôfre significativamente mais grande do que para os sólidos sulfatados pelo intercalação. Resumen en español El presente trabajo reporta los resultados de la caracterización química, estructural y textural de una vermiculita de origen colombiano modificada con especies simples de Zr y Ti, y el sistema mixto Ti-Zr en relaciones atómicas nominales Zr/(Ti + Zr) = 0,1 y 0,5. Adicionalmente, se evaluó la incidencia de la presencia de sulfato sobre los sistemas mencionados bajo las relaciones nominales sulfato/metal 0; 0,25 y 0,35, incorporando el sulfato ya sea en la solución in (mas) tercalante, o por impregnación vía húmeda sobre los sólidos modificados y calcinados. Los resultados indican que cuando la sulfatación se lleva a cabo por intercalación, la naturaleza química de la solución intercalante afecta notoriamente la cantidad de metal incorporado, dependiendo de la relación sulfato/metal empleada. De otro lado se estableció que, cuando se lleva a cabo la sulfatación por impregnación, las propiedades texturales, estructurales y morfológicas de los sólidos obtenidos se ven fuertemente afectadas y estan acompañadas de una fijación de azufre significativamente mayor que para los sólidos sulfatados por intercalación. Resumen en inglés The present work reports the results of chemical, structural and textural characterization of a Colombian vermiculite modified with simple species of Zr and Ti, and the mixed system of Ti-Zr in nominal atomic relations Zr/(Ti + Zr) = 0,1 and 0,5. Additionally, the incidence of sulfate presence was evaluated under the nominal relations sulfate/metal 0; 0,25 and 0,35, incorporating sulfate either in the intercalation solution, or by impregnation on modified and calcined sol (mas) ids. The results indicate that when the sulfation is carried out by intercalation, the chemical nature of the intercalation solution affects the amount of incorporated metal, depending on the relation used sulfate/metal. When the sulfation by impregnating is carried out, the textural, structural and morphologic properties of the obtained solids are strongly affected and are accompanied of a sulfur fixation significantly greater than for solids sulfated by intercalation.
