Sorption characteristics of o-cresol on bagasse fly ash and activated carbon

Bagasee flyash, a waste generated in sugar industry from bagasse fired boilers, was found to be a good adsorbent for o-cresol in aqueous solutions. Batch studies indicated that the percent removal decreased with increasing initial concentration of o-cresol. At the initial concentration of 100 mg dm -3 , 81 percent removal of o-cresol was obtained. Adsorption confirmed to both Freundlich and Langmuir isotherms. Kinetic modelling of the removal of o-cresol was obtained. Adsorption confirmed to both Freundlich and Langmuir isotherms, kinetic modelling of the removal of o-cresol was done using Lagergren first order rate expression. Column experiments indicated that the adsorbed amount of o-cresol decreased with increasing flow rate and decreased bed height. The BDST model was found applicable.
