Removal of Dye by Adsorption: A Review
Dye removal from industrial wastewater is an important environmental concern. So far, various physical and chemical treatment methods have been reviewed for the removal of dyes such as biological degradation, ion exchange, chemical precipitation, reverse osmosis, coagulation, flocculation, etc. However, these treatment processes have their limitations such as high cost, generation of toxic slud...
متن کاملInteraction of Anionic Azo Dye and TTAB - Cationic Surfactant
A interação entre três corantes aniônicos azo: C.I. Vermelho Ácido 14 (AR14), C.I. Vermelho Ácido 1 (AR1), C.I. Laranja Ácido 7 (AO7) e um surfactante catiônico, o brometo de tetradeciltrimetilamônio (TTAB), foi investigada por meio da técnica de eletrodo seletivo para surfactante. O eletrodo seletivo para TTAB foi construído e usado para determinar a concentração de monômeros TTAB e, também, d...
متن کاملAdsorption of Ethylene on Neutral, Anionic and Cationic Gold Clusters
The adsorption of ethylene molecule on neutral, anionic and cationic gold clusters consisting of up to 10 atoms has been investigated using density-functional theory. It is demonstrated that C2H4 can be adsorbed on small gold clusters in two different configurations, corresponding to the πand di-σ -bonded species. Adsorption in the π-bonded mode dominates over the di-σ mode over all considered ...
متن کاملAggregation of an anionic azo dye with conventional cationic surfactants in premicellar region: A conductometric study
The interaction of Congo Red CR with a series of Alkyltrimethylamoniumbromide CnTAB, N-hexadecylpyridinium bromide CPB and N-hexadecylpyridinium CPC were investigated using conductometry technique. It was observed that the formation of dye-surfactant ion pairs takes place at surfactant concentration far below the critical micelle concentration of the individual surfactants. Aggregation was refl...
متن کاملEffect of activation factors on adsorption of cationic dye, methylene blue, by activated bentonite
The aim of this investigation was to study the relationship between activation factors and adsorption of cationic dye, methylene blue MB, by activated bentonite. The adsorption index was investigated as a function of acid type, time and temperature. A commercial bentonite was selected as a starting material and the effect of heat treatment on MB adsorption were determined in a batch setup. Thou...
