Abstract
MéTODO DE FABRICAçãO DE ESFERAS ADSORVENTES DE ZEóLITA TIPO 4A VIA PROCESSO SOL-GEL APROPRIADAS PARA A ADSORçãO E CAPTURA DE METAIS PESADOS PRESENTES EM BAIXAS CONCENTRAçõES EM GRANDES VOLUMES DE EFLUENTES LìQUIDOS INDUSTRIAIS. A presente invenção diz respeito a um método de fabricação de esferas adsorventes de zeólita tipo 4A, o qual se baseia no conhecido Processo Sol-Gel para imobilizar micropartículas (<243>38 <109>m) de zeólita tipo 4A, preferencialmente na fase Na~ 2~O.A1~ 2~O~ 3~.1,85SiO~ 2~.5,1H~ 2~O, no formato esférico e colá-las com moléculas de álcool polivinílico (PVA) e com nanopartículas de bohemita (<244> -A1~ 2~O~ 3~.H~ 2~O), nanopartículas estas obtidas com auxílio de uma reação de transformação sol-gel à temperatura ambiente, em meio gasoso contendo NH~ 3~ e em um meio aquoso contendo NH~ 4~OH. As esferas de zeólita tipo 4A são obtidas com elevada esfericidade, resistência mecânica superior a 2 Kg/esfera, distribuição estreita de diâmetro, com diâmetro médio entre 1 mm e 5 mm, com boa estabilidade química em meios ácidos, básicos e neutros e com boa capacidade de absorver água sem levar a um inchamento destrutivo. Estas esferas são apropriadas para o tratamento alternativo de grandes volumes de rejeitos líquidos industriais contendo baixas concentrações de metais pesados, particularmente de Cd, Cu e Zn, já que elas podem ser obtidas industrialmente a baixo custo e com as seguintes características de adsorção para Cd+Cu+Zn: eficiência de remoção superior a 81%, capacidade adsortiva máxima de 746 <109>mo1/g e taxa de adsorção <242>18,3 <109>mo1/g.h.
