Abstract

Phenol and its derivatives are present in effluents from various industrial processes such as petroleum refining (produced water) and the pharmaceutical industry, being highly toxic. The present work elaborated a new catalyst for the removal of phenol and derivatives. NiNb was prepared with deposited platinum and its photocatalytic activity was tested on phenol degradation in sea and distilled water, in the presence and absence of UV light, with varying concentrations of platinum. The catalyst was characterized by XRD and DRS. The results of the study demonstrated that the NiNb catalyst with platinum deposited, achieved 65% phenol removal in seawater and about 57% in distilled water, both in the presence of UV light.
