Abstract
The photocatalytic degradation of phenol in visible light was Observed following different irradiation procedures. The reaction follows firs t-order kinetics, although adsorption effects appear, especially in th e case of Fe2O3 immobilized in ordinary beach sand. The apparent rate constant K(ap) and initial reaction rate are dependent on the pH, and reach a maximum at pH 5.5.
