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.

Creating photocatalytic materials to generate clean energy and for ecological detoxification has been a challenge as far as meeting the worldwide demand for energy and cutting pollution is concerned. Anti-inflammatory medicines and pharmaceutically active chemicals (PhACs) are frequently found in wastewater. Since conventional wastewater treatment facilities do not completely remove these micropollutants (pharmaceuticals), alternatives are required. It is still difficult to make an inert and efficient nano-photocatalyst like titanium dioxide (TiO2). TiO2 photocatalysts have been extensively utilized as innovative photocatalysts for treating contamination because of their distinctive physicochemical characteristics, less toxic nature, biological inertness, improved energy efficiency, low-temperature reaction conditions, insolubility in water, easy accessibility, highly stable chemical nature and natural environmentally friendliness. However, their large band gap energy, that can only be generated under UV light and quickly with charge carrier recombination, restricts their photocatalytic applications. Its band gap energy was additionally decreased in order to be active in visible light in a variety of methods. Recent research developments concerning the TiO2-based heterostructure as a photocatalyst as well as its modifications, factors and removal method are summarized in this review which concludes with an overview and viewpoints on the present difficulties as well as fresh lines of inquiry in this developing field of study.
