The activated carbon prepared from palm seed coat by dolomite process showe
d more than 95% removal of o-cresol from aqueous solution under optimum con
ditions. The adsorption capacity calculated by Freundlich adsorption isothe
rm gave 19.58 mg/g of o-cresol removal. The kinetic studies revealed the ov
erall 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 so
lution. Film diffusion was found to be the rate limiting step. Recovery of
used carbon was studied by in situ chemical regeneration technique and show
ed good result.
