| Gas phase adsorption of toluene, methyl ethyl ketone (MEK), and methyl isobutyl ketone (MIBK) on two types of activated carbons, BPL- bituminous base and OVC- coconut base, were investigated in this study. The adsorption isotherms were determined by using the constant volume approach. Each isotherm point was acquired using a 10-liter Tedlar bag. In order to confirm the accuracy of equilibration, three initial adsorbate concentrations were used for each adsorption isotherm study. Freundlich adsorption equation was found to adequately represent the experimental adsorption data. The toluene adsorption isotherms on the two activated carbons were found to be very similar in the range of 1 to 14 Pa. OVC provided better adsorption capacity for MEK and MIBK as compared to BPL in the range of 1 to 30 Pa. Ternary adsorption isotherms of these three compounds on both BPL and OVC were predicted well by the ideal adsorption solution theory (IAST). |
