The photocatalytically-assisted electrochemical degradation of ibuprofen (IBP) in basic
medium was carried by using Dimensionally Stable Anodes (DSA) with the composition
Ti/RuO2-TiO2 and Ti/RuO2/SnO2-Sb2O5-RuO2, and zeolite-supported TiO2 based on (Z-TiO2-
Ag and Z2-TiO2) photocatalysts. Also photoelectrochemical experiments were carried out for
assessment of photocatalysts contribution to IBP degradation. The experiments were carried
out by applying current densities of 200 and 300 A/m2 simultaneously with UV irradiation for
60, 120 and 180 minutes, and concentration of the photocatalysts of 1 g/L. The degradation
processes were monitored by recording the UV spectra and determination of Total Organic
Carbon (TOC). The best result for TOC removal efficiency was of 44.27% and it was
registered in the photocatalytically-assisted electrochemical degradation of IBP on Ti/RuO2-
TiO2 anodes and Z2-TiO2 photocatalyst at 300 A/m2 and 180 min of process duration.
