“…It was determined that all PPCPs degraded according to pseudofirst-order kinetics in the Fenton process. [59] Similar to this study, studies have generally shown that CBZ, [60] DFC, [61] IBU, [62] PRC, [63] and TRC [64] exhibit pseudo-first-order kinetics of photodegradation.…”

In conventional wastewater treatment plants, micropollutants mix with the aquatic environment because they cannot be removed entirely due to their nonbiodegradable structure. Advanced oxidation processes can be considered an alternative solution to this problem. In this study, five different pharmaceutical and personal care products, carbamazepine, diclofenac, ibuprofen, paracetamol, and triclosan, which are commonly found in aquatic environments, were selected as target pollutants. The removal of these target pollutants was investigated using advanced oxidation methods such as the Fenton and UV processes (UV, UV/H2O2, and UV/TiO2). The feasibility of processes in terms of cost was investigated. In the study, both initial and final pharmaceutical concentrations were measured using liquid chromatography mass spectrometry/mass spectrometry to accurately calculate removal efficiency. It has been determined that processes other than the UV process have removal efficiency >99.9%. The UV process showed removal efficiency of 40% for carbamazepine, 90% for diclofenac, 85% for ibuprofen, 86% for paracetamol and 85% for triclosan. Among the processes with high removal efficiency, the Fenton process has been integrated into wastewater treatment plants and has been shown to be the most suitable system in terms of both performance and cost in solving the micropollutant problem.

“…Nevertheless, the main removal TCS pathway from water sources is still oxidation. Particularly, photocatalysis is more appropriate for TCS removal from wastewater (Hippargi et al 2021 ; Kaur et al 2020 ). TCS is identified as biodegradable, photo-unstable, and chlorine and ozone readily reactive.…”

“…The graphene has good electrical conductivity and can be used as an acceptor of TiO 2 photogenerated electrons in SGT photocatalyst. [51][52][53][54] Therefore, the graphene not only leads to the spatial separation of the electrons and holes and then reduces the recombination rate, but also enhances the transfer of electrons from SGT composites to the targeted pollutants, thus increasing the lifetime of the charge carriers and thus improving the efficiency of the photocatalytic process. These electrons are captured by surface oxygen leading to the formation of •O 2 À .…”

The use of TiO2/graphene composites as catalysts for photodegradation of dyes has been widely investigated. TiO2/graphene composites are usually obtained by coating TiO2 on the surface of pre‐prepared graphene. However, graphene is prone to curling and stacking, which makes it difficult to uniformly coat TiO2 on its surface, resulting in poor photocatalytic performance. In this paper, a non‐conventional approach to prepare TiO2/graphene nanocomposites based on the use of porous SiO2/graphene spheres as supports is presented. SiO2/graphene spheres with intercalated structure and dendritic pores were prepared as supports by a one‐step hydrothermal method. Then, TiO2 was coated into the pores of SiO2/graphene spheres by sol‐gel method to obtain SiO2/graphene@TiO2 composites (SGT). After 90 min of visible light irradiation, the degradation rate of RhB by SGT catalyst was 68.9 %, which was significantly higher than that of P25 by 39.3 %. A mechanism of the RhB removal by the SGT composites was proposed.
