Resumen
Introduction. This research work consisted on the
removal of recalcitrant substances in water. They
are synthetic pollutants in waste water and can be
removed by the use of FeCl3 and TiO2, plus an
oxidation agent, like H2O2. This system allows the
use of artificial light for, with no intermediate stages,
provoke chemical reactions that bring the mineralization or the degradation of the pollutants dissolved
in the water studied. Objective. To find the optimal
conditions to treat waste waters with Novactive blue
FHBRNS, by the use of oxidation processes that
uses artificial light. Matetials and methods. A 60 Hz
MIGTHY PURE ultra-violet lamp was used, with a
glass cuvette that contained 15 L of the sample. The
sample was re-circulated with a pump, which had a
0.047L/s flow. Results. A 97.3% degradation rate
and a 65.8% mineralization rates were obtained with
FeCl3. In this same experiment the best degradation
and mineralization rates of the dye were obtained
with TiO2. Conclusion. The dye gets degraded and
mineralized faster with FeCl3. This took place in the
E7 trial (60 mg/L FeCl3 and 1.0 mL/L of H2O2).
