Laser-induced photo-catalytic degradation of phenol using WO3 was investigated for the first time. Effect of WO3 concentrations and laser energy on photo-catalytic removal of phenol from waste water was studied. Laser enhanced Photo-degradation can be an efficient method for the removal of phenol present in waste waters. The phenol removal process obeyed the first-order kinetics. (c) 2005 Elsevier B.V.
