The Degradation of Reactive Black Wastewater by Fe/Cu Co-doped TiO2

Abstract

The organic contaminant, REACTIVE Black 5 (RB5) was degraded by Fe/Cu co-doped TiO2 nano-particles under mercury lamp. In the present study, the combined effects of Fe/Cu doping amount, calcination temperature and calcination time on catalyst activity were investigated, and through quadratic regression general rotation design, the optimal condition for preparing the catalyst was obtained as follows: calcination time, 3.55h; calcination temperature, 453 ?; Cu doping amount, 1.89%; Fe doping amount, 1.62%.
