Adsorption of acetic acid from aqueous solution onto activated carbon was investigated to evaluate the effects of initial acetic acid concentration, contact time, nature of adsorbent and adsorbent dose on the removal of acetic acid systematically. The optimal contact time value for acetic acid adsorption onto the activated carbon was found to be 30 minute. Greater percentage of acetic acid adsorbed with increase in the initial concentration of acetic acid and increase in amount of adsorbent used. Adsorption data was modeled using the Langmuir and Freundlich isotherms. For all the samples, these data fitted well the Langmuir isotherm models in the range of the concentrations tested. Maximum amount of acetic acid adsorbed was 16.67 m mol/g. Adsorption of acetic acid onto treated sugar cane bagasse was highly favorable sorption than the activated carbon and the peels of banana.

Abstract
Adsorption of acetic acid from aqueous solution onto activated carbon was investigated to evaluate the effects of initial acetic acid concentration, contact time, nature of adsorbent and adsorbent dose on the removal of acetic acid systematically. The optimal contact time value for acetic acid adsorption onto the activated carbon was found to be 30 minute. Greater percentage of acetic acid adsorbed with increase in the initial concentration of acetic acid and increase in amount of adsorbent used. Adsorption data was modeled using the Langmuir and Freundlich isotherms. For all the samples, these data fitted well the Langmuir isotherm models in the range of the concentrations tested. Maximum amount of acetic acid adsorbed was 16.67 m mol/g. Adsorption of acetic acid onto treated sugar cane bagasse was highly favorable sorption than the activated carbon and the peels of banana.
