Influence of TiO2 dopant type upon cyclophosphamide degradation efficiency

"The influence of various dopant types like S, Fe, Co, Ni (5% wt.) in the photocatalytic degradation of cyclophosphamide under UV-VIS irradiation was investigated. The working conditions were as follows: irradiation time up to 270 minutes, photo catalyst dose 100 mg/L, initial pollutant concentration 19.15 mg/L. Pollutant degradation was found to follow a pseudo first order kinetic. CP degradation rate constants decreases
in the following order kFe-TiO2 > kNi-TiO2 > kCo-TiO2 > kS-TiO2 > kTiO2, which was also in accordance with chlorine mineralization rate constants."
