Resumen:
This study
is focused on the kinetic modelling of the Fenton and photo-Fenton degradation
of a model pollutant (atrazine) in aqueous solution. The effects of hydrogen
peroxide, ferric ion and radiation level on the degradation processes have been
investigated. The experimental work was performed in a well stirred tank
laboratory reactor irradiated from both sides with two tubular UV-lamps. The
reaction rate expressions are derived from an accepted reaction mechanism and
explicitly taking into account the local volumetric rate of photon absorption
existing in the photoreactor. Model predictions were compared with experimental
data, and a good agreement was obtained. The maximum root mean square error
(RMSE) for all the estimations was < 2%. The obtained results indicate that
Fenton and photo-Fenton processes are a possible way to improve the
biodegradability of a wastewater containing commercial atrazine.
