SORPTION OF ORGANICS FROM AQUEOUS-SOLUTION ONTO POLYMERIC RESINS

The uptake of phenol, toluene, chlorobenzene, and benzoic acid by seve ral polymeric resins and activated carbon was investigated experimenta lly. Presentation of the sorption data in terms of the number of sorbe d monolayers and fractional pore volume filled indicated that, for the polymeric resins, solute uptake cannot be viewed as only a surface ad sorption phenomenon. It is suggested that the aqueous phase uptake of phenol, toluene, chlorobenzene, and benzoic acid by the polymeric resi ns is attributable, in part, to solute absorption. The present study a lso suggests that solute uptake is affected by the swelling of some of the polymeric resins in water.
