Abstract
The adsorption and electrosorption of chloroform on three different gr anular activated carbon have been studied as a function of several par ameters such as temperature, pH and concentration. The adsorption was lower at neutral pH values. The adsorption capacity increased with an increase in the initial concentration or with a decreased temperature. The enthalpy was found to be about 10 kJ.mol(-1), which corresponds t o st physical adsorption. The double layer capacity was determined for two types of C.A.G.: 5 to 10 mF m(-2).
