“…However, for photolysis at pH initial 6.5, the COD was 83% and 11% after 3 h, whereas Méndez-Arriaga et al [23] showed the opposite in aqueous solution of 0.8 mmol/L; from their analysis, they noted that 3 h of photolysis process treatment resulted in 90% removal of NPX with just 5% of mineralization, but under the TiO 2 photocatalytic process, only 40% of removal and more than 20% mineralization resulted. As for antibiotics, many studies were observed in Table 3, [97,101,[105][106][107][108][109][110][111][112]; they all agree on the efficiency of the photocatalytic process for the removal of different antibiotics drugs such as Ciptofloxacin CIP, which was completely removed from urban wastewater even before 20 min of treatment when they added Fe 2+ and TiO 2 as catalysts in the wastewater treatment plants [101]. Additionally, this drug was eliminated under UVA light by combining two catalysts: TiO 2 and ZnO [109].…”

“…In real urban wastewater, they found a percentage between 89.83% and 100% of degradation after 40 min of treatment. Monteoliva-Garcia et al [101] used light-driven AOPs, which is a good treatment process for three different pharmaceuticals products: ibuprofen, carbamezapine, and ciprofloxacin in real urban wastewater. They demonstrated a removal of 80.4% to 100% of carbamazepine, an antidepressant drug, after 40 min of treatment in real urban wastewater, also from 89.83% to 100% for ibuprofen and a total removal for ciprofloxacin.…”

Removal of Pharmaceuticals from Water by Adsorption and Advanced Oxidation Processes: State of the Art and Trends

et al. 2021

Pharmaceutical products have become a necessary part of life. Several studies have demonstrated that indirect exposure of humans to pharmaceuticals through the water could cause negative effects. Raw sewage and wastewater effluents are the major sources of pharmaceuticals found in surface waters and drinking water. Therefore, it is important to consider and characterize the efficiency of pharmaceutical removal during wastewater and drinking-water treatment processes. Various treatment options have been investigated for the removal/reduction of drugs (e.g., antibiotics, NSAIDs, analgesics) using conventional or biological treatments, such as activated sludge processes or bio-filtration, respectively. The efficiency of these processes ranges from 20–90%. Comparatively, advanced wastewater treatment processes, such as reverse osmosis, ozonation and advanced oxidation technologies, can achieve higher removal rates for drugs. Pharmaceuticals and their metabolites undergo natural attenuation by adsorption and solar oxidation. Therefore, pharmaceuticals in water sources even at trace concentrations would have undergone removal through biological processes and, if applicable, combined adsorption and photocatalytic degradation wastewater treatment processes. This review provides an overview of the conventional and advanced technologies for the removal of pharmaceutical compounds from water sources. It also sheds light on the key points behind adsorption and photocatalysis.

“…Wang et al [ 9 ] observed that the degradation of IBU was directly affected by the pH of the solution, with the highest degradation rate (49.45%) in acidic pH values. The best photocatalytic yield for degradation at an acidic pH has been attributed to the adsorption of IBU on the surface of the catalysts due to the increase in electrostatic interactions between IBU and the photocatalyst [ 61 ].…”

“…The IBU degradation rate increased with the use of ZnO-Ce and ZnO-Ce in the presence of H 2 O 2 systems (ZnO-Ce + H 2 O 2 ) reaching about 60% and 70%, respectively. The improvement of the photochemical process can be linked to the interaction between the semiconductor and H 2 O 2 , increasing the photocatalyst sites and consequently facilitating the chemical interaction with IBU [ 61 ].…”

A Brief Photocatalytic Study of ZnO Containing Cerium towards Ibuprofen Degradation

et al. 2021

Ibuprofen (IBU) is one of the most-sold anti-inflammatory drugs in the world, and its residues can reach aquatic systems, causing serious health and environmental problems. Strategies are used to improve the photocatalytic activity of zinc oxide (ZnO), and thosethat involvethe inclusion of metalhave received special attention. The aim of this work was to investigate the influence of the parameters and toxicity of a photoproduct using zinc oxide that contains cerium (ZnO-Ce) for the photodegradation of ibuprofen. The parameters include the influence of the photocatalyst concentration (0.5, 0.5, and 1.5 g L−1) as well as the effects of pH (3, 7, and 10), the effect of H2O2, and radical scavengers. The photocatalyst was characterized by Scanning Electron Microscopy-Energy Dispersive Spectroscopy, Transmission electron microscopy, Raman, X-Ray Diffraction, surface area, and diffuse reflectance. The photocatalytic activity of ibuprofen was evaluated in an aqueous solution under UV light for 120 min. The structural characterization by XRD and SEM elucidated the fact that the nanoparticle ZnO contained cerium. The band gap value was 3.31 eV. The best experimental conditions for the photodegradation of IBU were 60% obtained in an acidic condition using 0.50 g L−1 of ZnO-Ce in a solution of 20 ppm of IBU. The presence of hydrogen peroxide favored the photocatalysis process. ZnO-Ce exhibited good IBU degradation activity even after three photocatalytic cycles under UV light. The hole plays akey role in the degradation process of ibuprofen. The toxicity of photolyzed products was monitored against Artemia salina (bioindicator) and did not generate toxic metabolites. Therefore, this work provides a strategic design to improve ZnO-Ce photocatalysts for environmental remediation.

Emerging pollutants (EPs) refer to a class of pollutants, which are emerging in the environment or recently attracted attention. EPs mainly include pharmaceutical and personal care products (PPCPs), endocrine-disrupting chemicals (EDCs), and antibiotic resistance genes (ARGs). EPs have potential threats to human health and ecological environment. In recent years, the continuous detections of EPs in surface and ground water have brought huge challenges to water treatment and also made the treatment of EPs become an international research hotspot. This paper summarizes some research results on EPs treatment published in 2019. This paper may be helpful to understand the current situations and development trends of EP treatment technologies.
