“…One of the challenging issues is that the pharmaceutical residues in wastewater are not exterminate or removed in many cases. Among the systematically used medicines, painkillers and antibiotics account for a signi cant share of the drugs consumed by humans and grassland animals [11][12][13] . For example, accordant with the World Health Organization (WHO), PC acts as a common nonsteroidal 14 , antiin ammatory 15 , and antipyretic drug 16 in the rst line of pain treatment by inhibiting cellular mediators involved in the initiation of pain.…”

This work presents a significant highly porous activated magnetic carbon nanoparticles (MPFRC-A) derived from pine fruit residue through physical activation (carbonization temperature: 110–550◦C), chemical activation (H2SO4 (0.1 N, 96%)), and Co-precipitation processes and then using it for removing tetracycline (TC) and paracetamol (PC) from water and evaluating via the spectrophotometer (DR6000). Functionalization of Fe3O4 nanoparticles on the surface of (PFR-AS) generated high saturation magnetization that causes to separate from aqueous solution by an external magnet. MPFR-AS adsorbent was evaluated by Brunauer-Emmet-Teller (BET) analyzer, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-Ray diffraction analysis (XRD) and Raman spectroscopy (RM). In the experimental sector, the effect of different items including, pH, contact time, initial concentrations, adsorbent dosage, and temperature on the adsorption processes were investigated and based on them the adsorption isotherm modules, and kinetics were studied and concluded. Results indicated that MPFR-A exhibited a large specific surface area (182.5 m2/g) and high total pore volume (0.33 cm3/g). The maximum adsorption capacity was obtained at pH = 4,5, adsorbent dose: 400 mg and initial concentration of 20 mg/L at 25°C. The study showed that experimental data were well-fitted by Langmuir isotherm model (R2 > 0.98) and the maximum uptake capacities for TC was 43.75 mg/g and for PC was 41.7 mg/g.

“…The presence of pharmaceutical compounds in various aquatic systems such as rivers, lakes, oceans, groundwater, and consequently in drinking water has been well documented (Bottoni 2010 ; Chander et al, 2016 ; Balakrishna et al, 2017 ; Lozano et al, 2022 ). The improper disposal and treatment of municipal and industrial effluents increased their levels in water sources (Miettinen et al, 2022 ; Dhanalakshmi et al, 2022 ). Residues of pharmaceuticals in water can affect the food and reproductive cycle of aquatic organisms and may even lead to their death due to the highly toxic effects of pharmaceuticals on natural fauna and flora.…”

Photo-driven advanced oxidation process (AOP) with pharmaceutical wastewater has been poorly investigated so far. This paper presents the results of an experimental investigation on the photocatalytic degradation of emerging pharmaceutical contaminant chloroquine (CLQ) in water using zinc oxide (ZnO) nanoparticles as the catalyst and solar light (SL) as the source of energy. The catalyst was characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), scanning electron microscopy-energy dispersive X-ray analysis (SEM-EDAX), and transmission electron microscopy (TEM). The effect of various operating parameters such as catalyst loading, the concentration of target substrate, pH, and the effect of oxidants and anions (salts) on the efficiency of degradation was tested. The degradation follows pseudo-first-order kinetics. Surprisingly, contrary to the observation in most photocatalytic studies, the degradation is more efficient under solar radiation, with 77% under solar (SL) irradiation and 65% under UV light in 60 min. The degradation leads to slow and complete COD removal through several intermediates identified by the liquid chromatography–mass spectrometry (LC-MS) technique. The results suggest the possibility of using inexpensive natural, non-renewable solar energy for the purification of CLQ-contaminated water, thereby enabling the reuse of scarce water resources.
