In water pollution control, treatment methodologies such as biological degradation, adsorption, ion exchange, chemical oxidation, membrane separations, incineration, and stream stripping, have been applied for the removal of organic contaminant, but the use of polymeric adsorbent resins is an interesting option for recovery where the economics of solvents or chemical regeneration of the adsorbent are favorable. Distribution equilibria have been investigated for the adsorption of phenol on two macroporous adsorbent resins (Amberlite XAD-4 and Lewatit OC-1064). The experiments were done using a batch technique. The effects of solution pH, temperature, and ionic strength were studied. Results with a new commercial resin (Lewatit OC 1064) have been compared with measurements on the well-established adsorbent resin Amberlite XAD-4. The Langmuir equation was selected to analyze the effect of pH, temperature, and ionic strength on the equilibrium. The influence of the pH has been interpreted in terms of the phenol dissociation. The fraction of free water has been considered in evaluating the influence of the sodium sulfate concentration.
