In many places of the world, water is a scarcity resource. The possibility of
reusing water increases the relevance of developing different water treatment
methods. The goal of this research has been to determine if the photo-Fenton
is efficient for the degradation of organic compounds as viable alternative for
wastewater treatments. To reach this goal, many objectives should be
previously satisfied, including the synthesis of different catalysts and the
catalytic tests for the different processes. Catalysts were characterized by XRD,
FE-SEM, SBET and TGA. For the photocatalytic activity a cylindrical reactor with
continuous stirring was used. The dye (10 -5 M) was previously dissolved in water
and 0.6g L -1 of the corresponding catalyst was added to the reaction
mixture. UV-vis irradiation (60 watts) was applied. An aliquot of 10 mL was
taken every 10 min during a period of an hour from the solution and diluted for
characterizing by UV-vis and fluorescence spectroscopies and TOC. Synthesized
(Fe 2 O 3 NWs and Fe 3 O 4 (Mag)) and commercial catalysts (FeCl 2 ) were fully
characterized by FE-SEM, TGA, specific surface area (BET) and XRD. The most
efficient catalysts were FeCl 2 during the photo-Fenton process (with
approximately 92.31% of degradation). All the catalysts used were able to
degrade the Methylene Blue and could eventually be used to removal pollutants
from water.
