“…Although common treatment processes are very efficient to remove suspended solids, biodegradable organic compounds, inorganic matter and pathogens, they fail to remove pharmaceuticals and antibiotics, in particular [1,35,44,45]. Biological treatment, which is the foundation of any WWTP, is simple and easy to operate, cost-effective and does not generate toxic by-products [39,41,46].…”

The extensive application of antibiotics in human and veterinary medicine has led to their widespread occurrence in a natural aquatic environment. Global health crisis is associated with the fast development of antimicrobial resistance, as more and more infectious diseases cannot be treated more than once. Sulfamethoxazole, trimethoprim and ciprofloxacin are the most commonly detected antibiotics in water systems worldwide. The persistent and toxic nature of these antibiotics makes their elimination by conventional treatment methods at wastewater treatment plants almost impossible. The application of advanced oxidation processes and heterogeneous photocatalysis over TiO2-based materials is a promising solution. This highly efficient technology has the potential to be sustainable, cost-efficient and energy-efficient. A comprehensive review on the application of various TiO2-based photocatalysts for the degradation of sulfamethoxazole, trimethoprim and ciprofloxacin is focused on highlighting their photocatalytic performance under various reaction conditions (different amounts of pollutant and photocatalyst, pH, light source, reaction media, presence of inorganic ions, natural organic matter, oxidants). Mineralization efficiency and ecotoxicity of final products have been also considered. Further research needs have been presented based on the literature findings. Among them, design and development of highly efficient under sunlight, stable, recyclable and cost-effective TiO2-based materials; usage of real wastewaters for photocatalytic tests; and compulsory assessment of products ecotoxicity are the most important research tasks in order to meet requirements for industrial application.

“…Due to the low efficiency of conventional wastewater treatment process, caffeine has been detected in many surface water and ground water [4; 5]. Several methods have been applied for treatment of pharmaceutical products like photocatalytic degradation [6], micro extraction [7], oxidation [8], biodegradation [9], chlorination [10], biofiltration [11], nanofiltration and reverse osmosis [12], electrochemical oxidation [13], and adsorption [14]. Adsorption process has been a prominent method of treating aqueous effluent in industrial processes for a variety of separation and purification purposes.…”

Caffeine is a chemical compound that has been detected in the environment and belongs to some of the most popular emerging pollutants that may cause serious environmental and human health problems. In this study, the adsorption of caffeine on groundnut shell as low cost adsorbent was investigated using the batch equilibrium method. Three adsorption isotherms namely the Langmuir, Freundlich and Redlich–Peterson isotherms in their non-linear forms were applied to the adsorption equilibrium data. Both the Langmuir and Redlich–Peterson models were found to fit the adsorption isotherm data well. The retention of caffeine on the groundnut shell showed a relatively significant adsorption with a maximal quantity of 4.21 mg g-1. The present study showed that the powdered groundnut shell is a promising and alternative adsorbent for the removal of caffeine from aqueous solutions.

“…[5][6][7][8] Among the advanced oxidation (AO) processes, light-driven photocatalytic degradation has received considerable attention due to its costeffectiveness, eco-friendly nature, and the absence of residual secondary pollutants. 9,10 Therefore, the modication or synthesis of novel photocatalysts for this purpose is a prime concern in the eld of AO. In this regard, multiple reports on the graphene-based multifunctional nanocomposites have been published for the photocatalytic degradation of water pollutants.…”
