Comparative kinetic study of atrazine photodegradation in aqueous Fe(ClO4)3 solutions and TiO2 suspensions

Original language description

Kinetics of oxidative photodegradation of atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) in both homogenous solutions of Fe(ClO4)3 and heterogeneous suspensions of TiO2 were investigated and compared. Comparing freshly prepared solutions of Fe(ClO4)3 with aqueous slurry of TiO2 P25 (Degussa), the photodegradation rates were similar. Colloidal suspensions of quantum sized particles Q-TiO2 were less photoactive than the P25 slurry. Doping of the quantum-sized particles by Fe3+ caused a red shift of the semiconductor absorption but influenced the photocatalytic activity negatively. Comparing to Q-TiO2, the degradation rate for Q-TiO2 (1% Fe3+) decreased while for the corresponding mixture of Q-TiO2 and 1% Fe(ClO4)3 it increased.
