Degradation of pesticides in water using solar advanced oxidation processes

Alachlor, atrazine and diuron dissolved in water at 50, 25 and 30 mg/L, respectively were photodegraded by Fe2+/H2O2, Fe3+/H2O2, TiO2 and TiO2/Na2S2O8 treatments driven by solar energy at pilot-plant scale using a compound parabolic collector (CPC) photoreactor. All the advanced oxidation processes...
