Resumo Inglês:

The intensive use and irregular disposal of pesticides in agriculture has
caused serious environmental and health problems. In this work was evaluated the
efficiency of UV and some advanced oxidation processes involving photo-Fenton reaction,
O3 and O3/UV for the treatment of aqueous solutions containing commercial and standard
pesticides. The results showed that the combination of UV radiation in alkaline means
with O3 significantly increased the efficiency of the process of degradation and the photoFenton system is a promising alternative for the treatment of effluents containing
pesticides.
