“…On the contrary, references to works published in the 1970s, 1980s, and 1990s have been reduced to a minimum. This paper follows the path of some previously published reviews dealing with the removal of antibiotics in water by AOPs [35][36][37][38][39][40][41][42][43][44][45][46][47].…”

In this work, the application of advanced oxidation processes (AOPs) for the removal of antibiotics from water has been reviewed. The present concern about water has been exposed, and the main problems derived from the presence of emerging pollutants have been analyzed. Photolysis processes, ozone-based AOPs including ozonation, O3/UV, O3/H2O2, and O3/H2O2/UV, hydrogen peroxide-based methods (i.e., H2O2/UV, Fenton, Fenton-like, hetero-Fenton, and photo-Fenton), heterogeneous photocatalysis (TiO2/UV and TiO2/H2O2/UV systems), and sonochemical and electrooxidative AOPs have been reviewed. The main challenges and prospects of AOPs, as well as some recommendations for the improvement of AOPs aimed at the removal of antibiotics from wastewaters, are pointed out.

“…AOP is efficient in the removal of hazardous pollutants and their mineralization into non-toxic inorganic aliphatic acid, CO 2 and water as compared to other decontamination techniques like; adsorption, coagulation, flocculation, sedimentation, bio-filtration, etc., as a result of the generation of active oxidizing agents such as hydroxyl radicals, superoxide, ozonide and photo-produced electron-hole pairs [10][11][12]. AOP can be achieved by direct ozonolysis, catalytic oxidation, homogenous/ heterogeneous catalyzed oxidation, with the more recent advances in photocatalytic oxidation which is one of the green technologies that has attracted scientific interest as viable alternatives for the treatment of wastewater because of its low operating cost, nontoxicity, and effective reduction of contaminants [13,14].…”

Pharmaceuticals and personal care products in water and wastewater: a review of treatment processes and use of photocatalyst immobilized on functionalized carbon in AOP degradation

The presence of emerging contaminants such as pharmaceutical and personal care products in many aqueous matrices have been reported. One of such matrix is streams of wastewater, including wastewater treatment plants inflows and outflows and wastewater flow by-passing wastewater treatment plants. Their persistence arises from their resistant to breakdown, hence they may remain in the environment over long time, with a potential to cause adverse effects including endocrine disruption, gene toxicity, the imposition of sex organs, antibiotic resistance and many others in some aquatic organisms exposed to arrays of residues of pharmaceutical and personal care products. Among the treatment techniques, advanced oxidation processes have been reported to be a better technique through which these PPCPs can be degraded in the WWTPs. Heterogeneous photocatalysis using various photocatalyst immobilized on solid support such as activated carbon, graphene and carbon nanotubes in AOPs have been shown to be a viable and efficient method of PPCPs degradation. This is because, the performance of most WWTPs is limited since they were not designed to degrade toxic and recalcitrant PPCPs. This review highlight the occurrence, concentration of PPCPs in wastewater and the removal efficiency of heterogeneous photocatalysis of TiO2 immobilized on solid supports.

“…The concept is based on the generation of highly reactive oxygen species (hydroxyl radical, superoxide anion radical, hydroperoxyl radical, alkoxyl radical), with the main feature consisting in their ability to mineralize unselectively the organic pollutants to carbon dioxide, water and inorganic ions or acids [27]. Hence, this process was successfully applied for the destruction of various dangerous organic substances from wastewaters [28][29][30]. It involves the pollutants transfer to the surface of a photocatalyst (titanium dioxide, zinc oxide, tungsten trioxide, strontium peroxide, zirconium dioxide, iron (III) oxide, cerium (IV) oxide etc.)…”

In recent years, more and more pollutants (including pharmaceuticals, personal care products, pesticides, herbicides, hormones, chemicals) are detected in the aquatic environment. Even if they are encountered in very low concentrations, the toxicological data reveal that they represent a major risk both for the water living organisms and for human beings. Moreover, an important resistance to the classical methods applied at wastewater treatment plants characterizes them. Aeration, coagulation, flocculation, sedimentation, filtration, adsorption, oxidation, activated sludge treatments are often either insufficient or completely ineffective. To overcome these drawbacks, many researches were dedicated to the development of new effective techniques for the removal of these water pollutants. Advanced oxidation methods are widely reported as being of the most efficient ones. In this article, we investigate the utility of the photocatalysis as a sustainable alternative for the enhanced elimination of an emergent water micropollutant. We evaluate here the impact of several parameters (catalyst type and concentration, contaminant concentration, radiant flux intensity) on the process efficiency. The targeted compound involved in the experiments was the pentoxifylline (a drug used in the treatment of diseases such as diabetic neuropathy, osteoradionecrosis or hepatic fibrogenesis). The registered pollutant removal rate under the selected reaction conditions (photocatalyst type: ZnO; photocatalyst concentration: 0.5 g/L; incident light flux: 9.52 mW/cm2; natural pH) reached values near to 100 % providing new insights on the viability and the efficiency of the evaluated methodology.
