Title
Ru/TiO2 catalyst for efficient removal of estrogens from aqueous samples by means of wet-air oxidation
Abstract

The ubiquitous presence of endocrine-disrupting compounds (EDCs) in the environment is mainly the consequence of their incomplete removal from biological wastewater treatment plants. One of the promising options for EDC removal is catalytic wet-air oxidation (CWAO), where pollutants are oxidized by activated O2 species in the presence of a solid catalyst. 17β-estradiol (E2) was used in CWAO experiments conducted in a trickle-bed reactor up to 230 °C over TiO2 and Ru/TiO2 solids. In the given range of operating conditions, E2 undergoes noncatalytic and catalytic oxidation routes. The employed Ru(3.0 wt.%)/TiO2 catalyst enabled complete and long lasting efficiency of E2 degradation as well as removal of estrogenicity from the feed solution. No deactivation occurred and no carbonaceous deposits were accumulated on the catalyst surface.
