Abstract
de Cd, Zn e do azul de metileno de soluções aquosas foi investigada. O material zeolítico preparado com a
cinza de carvão do filtro manga apresentou a eficiência de remoção mais alta para os poluentes. A seletividade
aos íons metálicos deste produto foi determinada como: Cd 2+ > Zn 2+ . As capacidades máximas de adsorção
encontradas foram 36,1 mg g -1 para o Zn 2+ , 76,3 mg g -1 para o Cd 2+ e 3,93 mg g -1 para o corante.
