The activated carbon prepared from palm seed coat by dolomite process showed more than 95% removal of o-cresol from aqueous solution under optimum conditions. The adsorption capacity calculated by Freundlich adsorption isotherm gave 19.58 mg/g of o-cresol removal. The kinetic studies revealed the overall rate constant decrease with increasing concentration of o-cresol. The activated carbon showed reversible uptake of o-cresol and thus have a good application potential for the removal/recovery of o-cresol from aqueous solution. Film diffusion was found to be the rate limiting step. Recovery of used carbon was studied by in situ chemical regeneration technique and showed good result.
