Mesoporous materials of the type MCM-41 were synthesized
using rice husk as precursor of silica. The MCM-41 support was
then modified with Fe by the wet impregnation method. The
synthetized catalysts were used as heterogeneous catalysts, in
the degradation of different endocrine disruptors in aqueous
medium, as herbicides (atrazine), compounds derived from the
plastic industry (bisphenol A) and the pharmaceutical industry
(acetaminophen), applying the photo-Fenton heterogeneous
reaction (Fe2+/H2O2/UV-Vis).Thus, a stable, effective and
sustainable solid was obtained which, at pH close to neutral
consumed low amounts of oxidant and provided an efficient
catalytic process to degrade recalcitrant organic molecules.
Consequently, the heterogeneous Fenton reaction presented in
this work appears as a promising pre-treatment capable to
improve the biodegradability of waste water from different
industry
