Adsorption of ethyl violet dye in aqueous solution by regenerated spent bleaching earth.
The adsorption of basic dye (i.e., ethyl violet or basic violet 4) from aqueous solution onto the regenerated spent bleaching earth (RSBE) was carried out by varying the process parameters such as initial concentration, pH, and temperature. As analytical comparisons, activated bleaching earth (ABE) was also used as adsorbent for the adsorption of the basic dye at various initial concentrations....
متن کاملThermodynamics of adsorption at the aqueous-air interface.
A thermodynamic model is presented for the aqueous-air interface. For common organic solutes a relationship between the activity coefficients in the bulk solution and on the surface layer is deduced by using the concept of a surface monolayer. This relation has enabled development of an equation expressing the air-water surface adsorption coefficient as a function of bulk activity coefficients,...
متن کاملAdsorption kinetics and thermodynamics of Malachite Green from aqueous solutions onto expanded Graphite nanosheets
Expanded graphite nanosheets (EG-nanosheets) were used for adsorption of Malachite Green (MG) from aqueous solution. The influences of dye concentrations, absorbent dosage, pH values and the temperatures on the adsorption were investigated as well. The dye adsorption experiments were carried out by utilizing batch procedure. EG-nanosheets were initially characterized by scanning electron micros...

متن کاملReactive dye extraction utilizing regenerated bleaching earth
Bentonite bleaching earth is utilized for purifying used motor oil through a recovery process in order to improve the quality and stability of the final product. Indeed, spent bleaching earth is generated due to adsorbing oil impurities. Polluted spent bleaching earth contains 20-40% (w/w) oil and is flammable. Its disposal without pre-treatment leads to loss of oil along with environmental imp...
