ADSORPTION OF PHENOLS ONTO MACRORETICULAR RESIN PARTICLES

Experimental uptake curves were collected by a shallow, bed technique at 298.2 K. Adsorbent particles employed were macroreticular (MR) resi ns and adsorbates were phenol and its derivatives. From the uptake cur ves and equilibrium data obtained by the so-called, batch bottle techn ique, equilibrium and kinetic parameters were determined and the effec ts of functional groups within both adsorbate molecules and adsorbent particles on those parameters are discussed. From the results, it beca me clear that physical and chemical properties, surface area of adsorb ent functional group, and solubility of adsorbates affected adsorption equilibria. Also, nitro-functional groups seemed to hinder adsorption equilibria and kinetics. Results can be explained by the resonance ef fects of functional groups.
