Potencial de resíduo não processado proveniente da obtenção do silício metálico como adsorvente do corante vermelho de metila

Abstract: RESUMO Efluentes industriais contendo contaminantes orgânicos e inorgânicos são despejados em mananciais causando prejuízo aos organismos aquáticos e, consequentemente, sérias doenças ao ser humano. Nesta pesquisa foi investigada a capacidade de adsorção frente ao azo corante vermelho de metila pelo resíduo industrial proveniente da fabricação do silício metálico, os resultados foram ajustados aos modelos de isotermas de adsorção de Temkin, Freundlich e Dubinin-Radushkevich. Realizou-se a caracterização granul… Show more

“…The high content of the carbon and oxygen elements the samples represents the morphological and structural conservation of the surface fibers, providing a high degree of active coordination sites (-COOH and -COO − ) [3 The elementary difference in surface morphology is the presence of small stomat silicon bodies exposed due to the dissolution of lignin and hemicellulose after the ments [32]. They may be providers of coordination bonds and capture dye molecu different natures, cationic or anionic [33,34].
