(Universidade Federal de Santa Maria, 2017-07-17)
Colored effluents containing dyes are generated in different industrial sectors, such as textiles, cellulose,
paper, leather, paint, among others. The treatment of these effluents is a current environmental problem, ...
Geopolímero mesoporoso obtido a partir de metacaulim e cinza de casca de arroz como alternativa de adsorvente para remoção de corantes
(Universidade Federal de Santa Maria, 2017-08-11)
The industrial activity has contributed greatly to a significant increase in the concentrations of dyes in water, representing an important source of contamination of the water bodies, especially when we consider that such ...
Utilização de caulim como um potencial adsorvente de baixo custo na remoção de poluente orgânico em soluções aquosas
(Universidade Federal de Santa Maria, 2017-03-24)
Dye industries have great difficulty in effectively treating of wastewater generated, particularly in relation to dyes removal of the effluents, that even in small quantities, gives intense color, contributing to contamination ...
Solução numérica de modelos de transferência de massa difusivos em sistemas de adsorção
(Universidade Federal de Santa Maria, 2017-07-17)
The present work develops in detail the numerical solution of diffusion mass transfer models
in the adsorption process of cationic dyes. The diffusive models are developed based on the
mass transfer phenomena in a porous ...
