“…Specifically, ERY and CBZ were the pharmaceuticals with the lowest degradation rates, showing maximum removal percentages of 45% and 61%, respectively, in combined SOLAR + UV-LED mode. This can be attributed to the neutral character of both compounds, which hinders their protonation at neutral pH, decreasing their reactivity, so, to obtain higher efficiencies, it would be necessary to work at lower pH values (when the pH is much lower than p K a) [ 61 , 62 ].…”

Today, the emergence of increasingly restrictive treatment and reuse policies make the implementation of full-scale tertiary treatment, capable of improving the quality of water, a priority. Full-scale TiO2 photocatalysis systems are resulting in a promising option, since TiO2 is commercially available. However, questions such as how to work continuously during day/night irradiation cycle, or the removing of TiO2 in outlet flow are still unresolved. In this work, a full-scale system integrating a solar CPC/UV-LED step combined with commercial microfiltration membranes was installed in a conventional WWTP for agricultural reuse purposes. After optimization, 0.5 g/L of catalyst and combined SOLAR + UV-LED showing the highest pharmaceutical removal percentages, while a self-designed UV-LED included in the own reaction tank resulting in higher efficiencies compared with commercial lamps. Longer membrane surface area decreased fouling problems in the system. However, 60 min of irradiation time was necessary to reach the most restrictive water quality values according with (EU 2020/741). After optimization step, total costs were reduced by 45%. However, it was shown that a reduction in operating and maintenance costs, along with the development of more effective and economical commercial filtration membranes is a key factor; therefore, working on these aspects is essential in the treated water cost reduction.

“…To remove dyes, a number of separation methods, such as physical and chemical ones (membrane filtration, coagulation, flocculation, and adsorption) (Alardhi et al 2023) biological ones (anaerobic and aerobic treatment) (Vashisht et al 2022), and chemical ones (photo-Fenton reaction, ozonation) (Tanveer et al 2022). In order to completely mineralize hazardous and non-biodegradable molecules, heterogeneous photocatalysis is favored, circumventing the drawbacks of physical and biological approaches (Ashraf et al 2022).…”

Triple transition (Ni, Cu, and Zn) doped hematite nanoparticles (α-Fe2O3 NPs) have made significant advances in biological, environmental, as well as other interdisciplinary fields of study, due to their stability and relative lack of toxicity. The α-Fe2O3 NPs has been made simple, effective, and ecologically benign by utilizing the reducing and capping capability of Azadirachta indica aqueous leaf extract. Synthesized material has been studied by XRD, UV-visible, Raman, FTIR, VSM, SEM, and TEM techniques. Doped α-Fe2O3 NPs possessed a rhombohedral phase and corundum structure that was exceptionally pure and well crystalline. The synthesized α-Fe2O3 NPs had a size of 22.83 nm and were irregular-spheroidal in shape, according to SEM and TEM examination. Synthesized NPs show ferromagnetic characteristics, according to VSM research. The photocatalytic activity of doped α-Fe2O3 NPs was evaluated by methyl orange (MO) (95%), methylene blue (MB) (97%), congo red (CR) (92%), and eosin yellowish (EY) (90%) efficiently dyes degradation, when exposed to visible light for 90–100 minutes. As a result, the NPs are suited for applications where reusability is a crucial essential feature due to the modest drop in the photocatalytic activity after four cycles. This current study examines the effects of α-Fe2O3 NPs on the seed germination of Vigna radiata (mung bean) and phytotoxicity study biomass accumulation Allium cepa (onion) through a series of germination assays. For this reason, it is crucial to manage the materials size, morphology, and magnetic properties in order to produce well-tailored photocatalysts.

“…This can affect the population of microorganisms in the environment, contributing to the emergence of resistant strains. Furthermore, they pose potentially toxic risks to aquatic organisms and may be absorbed eventually by humans through the food chain and drinking water (Ashraf et al 2022 ; Yi et al 2016 ).…”

An inexpensive and environmentally friendly composite synthesized from rice husk, impregnated with montmorillonite and activated by carbon dioxide, was investigated for the removal of azithromycin from an aqueous solution. Various techniques were used to characterize adsorbents in detail. The sorption process was primarily regulated by the solution pH, pollutant concentration, contact duration, adsorbent dose, and solution temperature. The equilibrium data were best analyzed using the nonlinear Langmuir and Sips (R 2 > 0.97) isotherms, which revealed that adsorption occurs in a homogenous manner. The adsorption capacity of pristine biochar and carbon dioxide activated biochar-montmorillonite composite was 33.4 mg g −1 and 44.73 mg g −1 , respectively. Kinetic studies identified that the experimental data obeyed the pseudo-second-order and Elovich models (R 2 > 0.98) indicating the chemisorption nature of adsorbents. The thermodynamic parameters determined the endothermic and spontaneous nature of the reaction. The ion exchange, π-π electron-donor–acceptor (EDA) interactions, hydrogen-bonding, and electrostatic interactions were the plausible mechanisms responsible for the adsorption process. This study revealed that a carbon dioxide activated biochar-montmorillonite composite may be used as an effective, sustainable, and economical adsorbent for the removal of azithromycin from polluted water.
