Abstract(s)
Solar hardware design for photocatalytic processes includes
aspects of optics, geometry and reactor materials. Compound
parabolic collectors (CPCs) have widely been used to promote
heterogeneous and homogeneous photocatalytic reactions. In this
work, different reflective surface (RS) materials (anodized
aluminum with [MS] and without [R85] protective coating, soiled
aluminum [R85s] and stainless steel [SS]) and geometries (flat [F],
single piece-double parabola [SP] and two pieces-double parabola
[DP]) were tested aiming the degradation of a recalcitrant organic
compound, gatifloxacin (GAT), by using a heterogeneous TiO2
photocatalytic system. Firstly, the photonic flux entering the
system was measured by 2-nitrobenzaldehyde actinometry,
considering the different RSs. After that, the catalyst (TiO2-P25)
was immobilized in the surface of a static mixer and axially
inserted in the tubular borosilicate photoreactor. Finally, the
efficiency of the heterogeneous photocatalytic system was
evaluated for GAT removal from aqueous solution using the best
photoreactor configuration.
