“…It must be pointed out that the effect of this parameter in photocatalytic degradation is very complex. The explanation of its influence can be associated with the modification of the charge of the semiconductor surface, the concentration of hydroxyl radicals generated during the photocatalytic reaction, and the ionization state of the target molecule [50,51]. Also, under acidic or alkaline conditions, the ionization state of the catalyst surface may be protonated or deprotonated according to the following equations:…”

This work demonstrates new evidence of the efficient destruction and mineralization of an emergent organic pollutant using UV-A and titanium nanosized catalysts. The target compound considered in this work is the primary metabolite of a lipid regulator drug, clofibrate, identified in many studies as refractory during conventional wastewater treatment. The photocatalytic performance study was carried out in batch mode at laboratory scale, in aqueous suspension. Kinetic data showed that titanium dioxide P25 Aeroxide® exhibits the highest photocatalytic efficiency compared to the other investigated catalysts. Pollutant degradation and mineralization efficiencies strongly increased when decreasing the initial substrate concentration. Target molecules oxidized faster when the catalyst load increased, and the mineralization was enhanced under acidic conditions: 92% of mineralization was achieved at pH 4 after 190 min of reaction. Radical quenching assays confirmed that HO• and ( h vb + ) were the reactive oxygen species involved in the photocatalytic oxidation of the considered pollutant. In addition, further results revealed that the removal efficiency decreased in real water matrices. Finally, data collected through a series of phytotoxicity tests demonstrated that the photocatalytic process considerably reduces the toxicity of the treated solutions, confirming the process’s effectiveness in the removal of persistent and biorefractory emergent organic water pollutants.

“…However, applications for another important emerging pollutant's category like flame retardants have been investigated in a lesser extent. The existing studies are focused mainly on tetrabromobisphenol A and other polybrominated diphenyl ethers (PBDEs) [29][30][31][32][33] whereas for organophosphorus flame retardants (OPFRs), which have replaced the banned PBDEs, the data are very scarce [34]. OPFRs are extensively used in various different applications [35,36] and they can migrate from the host materials into surrounding environmental media relatively easily by volatilization, leaching and/or abrasion due to the non-chemically bonded incorporation for many of them in the material matrices [36].…”
