Photo-Fenton treatment of valproate under UVC, UVA and simulated solar radiation.

The abatement of valproic acid sodium salt (VA) via photo-Fenton process was investigated to evaluate the effect of irradiation type. Three different light sources have been used: UVA (black light blue lamps, BLB reactor), UVC (UVC reactor) and simulated sunlight in a Solarbox (SB). Using the highest concentrations of Fe (10mgL) and HO (150mgL), 100% of VA degradation was observed in BLB and UVC devices, and 89.
