Abstract
A study of the competitive adsorption of organic compounds onto granul ar activated carbon was made with or without electrochemical polarisat ion of the adsorbent. Chosen models were chloroform/benzoic acid and c hloroform/phenol. Without polarisation the presence of a second compou nd in the solution induces a, reduction of the adsorption of the first one. A positive polarisation increases adsorption of chloroform, redu cing those of phenol or benzoic acid. A negative polarisation has the inverse effect. A molecular model is proposed to justify these phenome na.
