Resumen
Introduction. Prevention and control of environmental
pollution is one of the main responsibilities
and preoccupations of modern men. In recent years,
a significant number of research works have been
being done in order to prevent and control of such
pollution. Among these, photodegradation of
pollutants is a part of the advanced oxidation
technologies, which aims to reduct and/or elliminate
toxic and persistent compounds such as pesticides,
which are now part of the environment. Objective.
To evaluate the photo degradation of the Mertect
pesticide, by the use of photofenton with an ultra
violet light lamp. Materials and methods. An experimental
factorial 2x3 design was used, and an ultra
violet light lamp was used for it. Also, a glass vat
was used to keep the pesticide solution to be
degraded and a bomb that allowed the solution´s
re- circulation through the treatment system. The
pesticide’s degradation was determined by the use
of visible/ultra violet espectrophotometry. Results.
The highest percentage of degradation was
achieved with the use of hydrogen peroxide as an
oxidation agent (98,7%), followed by the
photochemical processes of the photofenton in an
experimental combination of 50 mg/L of iron and
1% v/v of hidrogen peroxide (95,6%). Conclusion.
Advanced oxidation processes are adequate for
wiping and elliminating Mertect pesticide.
