Abstract

Removal of pyruvic acid from water has been studied through catalytic ozonation. Copper or cobalt impregnated MCM-41, Ru-Al2O3, Ru-CeO2, FeO(OH) and LaTi1-xCuxO3 and LaTi1-xCoxO3 Perovskites have been used as catalysts. Only perovskites and Ru-CeO2 catalysts did show significant catalytic activity to increase the ozonation of pyruvic acid.
