Análise do Tratamento Químico em Carvão Ativado para Remoção do Corante Azul 5g
Palavras-chave:
Adsorção. Leito Fixo. Funcionalização.
Resumo
A maioria dos estudos em adsorção são realizados em sistemas batelada, que são limitados a escala laboratorial e tem menor aplicação nos processos industriais. Os leitos fixos são particularmente interessantes devido à sua fácil operação e possibilidade de regeneração sem que o leito seja desmontado. Assim, o presente trabalho teve por objetivo estudar o equilíbrio de adsorção do corante reativo azul 5G utilizando carvão ativado de osso de boi bruto e tratado com NaOH, em sistemas de leito-fixo. Testes dinâmicos foram realizados com o fluxo ascendente em coluna, a 30 °C e diâmetro médio de partícula de 0,0765 mm. A vazão ótima de trabalho encontrada para ambos os adsorventes foi de 2 mL min-1. As isotermas foram obtidas pelo balanço de massa nas curvas de ruptura, e foram ajustadas aos modelos de Langmuir e Freundlich. O carvão ativado de osso de boi demonstrou ter potencial para ser usado como um adsorvente alternativo na remoção do corante azul 5G presente em efluentes têxteis. E na adsorção também foi verificado que a funcionalização da superfície química do carvão não foi significativa no processo.
