Resumen:
The aim of this work was to study the degradation kinetics of
endocrine disruptor Benzyl Butyl Phthalate by a water treatment
process based on Ozone and UV radiation. The explored
variables were: (i) Ozone concentration, (ii) Incident radiation rate
at the reactor windows, (iii) reaction pH and (iv) presence of
radical scavengers. The model comprises four parallel subsystems:
(1) direct photolysis, (2) direct ozonation, (3) complete
ozonation reactions (direct + indirect oxidation) and (4) ozone +
UVC degradation.
Major intermediates of BBP degradation were identified, and a
degradation scheme was proposed. Degradation kinetics was
correctly modelled by a pseudo-first order kinetic model based on
the sum of all the effects occurring during the treatment, and the
corresponding kinetic constants were obtained.
