Catalytic ozonation of phenol using copper coated pumice and zeolite as catalysts.

Background: Catalytic ozonation has recently been applied as a new method of contaminant removal from water and wastewater. In this study, copper coated pumice and zeolite were used to catalyze the ozonation of phenol as a target pollutant from aqueous solutions.

Methods: The pumice and zeolite stone were modified by CuSO4 (1N).
