| Abstract |
Preferential adsorption of organic compounds onto activated carbon from dilute aqueous solutions was studied to develop a comprehensive theoretical basis for predicting adsorption of multicomponent solutes. The authors investigated in this research program a comparison of different carbons, the adsorption behavior with variable aqueous solution properties, and the difference between gas and liquid phase adsorption. The overall objective was to develop and test the comprehensive solvophobic theory. Experimental adsorption isotherms of a series of alcohols on five different carbons were measured and compared. Isotherms were run for 4-n-propyl phenol at various concentrations of ammonium sulfate salt and methanol as the additives to increase or decrease surface tension of solution, respectively. Also, isotherms for three linear carboxylic acids were measured at different pHs to determine the effect on adsorption. An experimental-glass vacuum system has been designed and built to measure adsorption isotherms in the gas phase. A comparison of measurements of adsorption isotherms for four alcohols in the aqueous and gas phases was conducted and confirmed the theoretical model. |
