Description :
Adsorption equilibrium and kinetic studies of phenols and substituted phenols at Para position in an aqueous phase was carried out in the present study. The adsorbent used in study was Granular Activated Carbon (GAC). Bituminous type of coal was source of the granular activated carbon (GAC). The mesh size of GAC used in the study was 12X16. GAC used in the study had already examined for surface area pore size and morphology in previous publication. The surface area of GAC was found to be 998 m2/g and loosely bounded and of open pores morphology. The adsorbates selected for these studies were phenol and its para substituted derivative namely; phenol, p-Methoxy Phenol and p-Nitro phenol. The order of adsorption for adsorbates was found to be p-Methoxy Phenol > p-Nitrophenol > Phenol. Functional group at para position was found to alter the adsorption behavior.
