摘要：

The photocatalytic degradation of phenol in visible light was Observed following different irradiation procedures. The reaction follows first-order kinetics, although adsorption effects appear, especially in the 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.
