Abstract
Adsorption isotherm of ethyl acetate (EA), a toxic volatile organic compound, is studied in E-Merck 13X molecular sieve at three different temperatures 35, 45, and 55 °C. Freundlich, Langmuir, and Langmuir–Freundlich isotherm model parameters and their temperature dependencies, saturation capacity, and heat of adsorption are found out from the experimental data. Isosteric heat of adsorption is determined using Clausius–Clapeyron equation and experimental data. Mass transfer coefficient of ethyl acetate is evaluated using Uptake curve method. Results show that the isotherm is of Brunauer type-I and was well fitted with both Langmuir and Langmuir–Freundlich isotherm models. Heats of adsorption from Langmuir isotherm model and isosteric heat of adsorption are comparable and are in the order of 10 5 J/kg. Overall mass transfer coefficient values are in the order of 10 −4 s −1.
