Sobre IBD

Este livro aborda a utilização de materiais adsorventes modificados à base de bentonite para o tratamento de água contaminada por compostos orgânicos fenólicos. São explorados três tipos de modificação: ativação ácida por H3PO4, funcionalização por quitosano e intercalação de surfactantes (CTAB). Os materiais assim obtidos são caracterizados utilizando várias técnicas (XRD, FTIR, SEM-EDX, TGA-DTA) para analisar as alterações estruturais e morfológicas. A adsorção é estudada em função de vários parâmetros (pH, tempo, temperatura, concentração) e os resultados são interpretados através de modelos cinéticos, isotérmicos e termodinâmicos. Os dados experimentais mostram uma melhoria significativa da capacidade de adsorção após a modificação. Os testes de regeneração confirmam a estabilidade e a possibilidade de reutilização dos materiais. Este trabalho abre perspectivas para a utilização destes materiais em aplicações sustentáveis de tratamento de água.
