Devido ás suas propriedades físicas favoráveis, associados á alta estabilidade física e química em condições normais, materiais naturais, como as zeólitas, têm sido amplamente aplicadas no tratamento de águas residuárias para remover poluentes. A capacidade de troca catiônica de uma zeólita natural brasileira, identificada como escolecita, tem sido avaliada para aplicação no controle de águas residuais. No presente trabalho o potencial da escolecita para remoção de metais tóxicos (Cd2+ , Cr3+ e Pb2+ ) foi investigado. Os efeitos do pH, da temperatura e da concentração de metais em solução durante o processo de adsorção foram avaliados. Isotermas descrevendo o mecanismo de adsorção foram obtidas utilizando-se soluções contendo 50 mg.L-1 de c...
