“…Among the drugs studied, DC had the highest concentration, reaching a value of 548.2 μg.L -1 . This drug is known as the most administered analgesic in the world (Carvalho Filho et al, 2022) and is frequently detected in aquatic matrices (Hanif et al, 2020). Similar results were observed by Rivera-Jaimes et al ( 2018) in the Apatlaco River in Mexico, where DC was detected in 100% of the samples.…”

This work aimed to analyze the presence of four common molecules (diclofenac, dipyrone, ibuprofen, and paracetamol) in the Ipojuca River, in the stretch of Caruaru municipality (Brazil), and in a wastewater treatment plant that discharges treated water to the river. Collections were conducted for three months at each point during April, May, and June. The samples were collected in three repetitions (sample, replica, and triplicate). Through Pearson’s correlation, the correlation between ibuprofen and diclofenac concentration and rainfall in the region was also verified. These drugs were detected in 100% of the samples, with concentrations between 7.4–548.2 and 81.8–231.8 μg.L-1, respectively. Paracetamol and dipyrone were not detected. The observed high concentrations are due to the high consumption of drugs and the low rate of sewage collection in the municipality. Both analyzed drugs — ibuprofen and diclofenac — had insignificant correlation results with rainfall (-0.022 and -0.071, respectively). Regarding the drugs in the WWTP, the treatment consisting of anaerobic followed by aerated lagoons showed efficiency ranging from 35.9 to 93.6% in the removal of diclofenac. The removal of ibuprofen was higher in April (86.6%), but in the other two months, it did not prove to be efficient, evidencing the need to implement more adapted technologies in the removal of drugs combined with the network expansion for sewage collection in the region. A study with longer time monitoring is needed to understand the rainfall effect on drug concentration in the river.

“…Worldwide, the global consumption of diclofenac (DCF), especially used in the treatment of inflammation and pain [ 33 ], has been estimated at approximately 940 tons per year, from which approximately 65% of the oral dose of this drug is released through urine and feces, along with its active metabolites, and passes through conventional wastewater treatment plants [ 34 ]. DCF is also found in waters due to improper disposal as solid waste or due to ineffective conventional treatments through effluents from industrial and urban wastewater treatment plants [ 35 ]. The European Commission defined limits of chronic toxicity with respect to the annual average and acute toxicity for DCF, establishing the maximum allowable concentrations between 0.1 and 0.01 μg/L for surface inland waters and between 75 and 7.5 μg/L for coastal waters [ 8 , 36 ].…”

The removal of pharmaceutical contaminants from wastewater has gained considerable attention in recent years, particularly in the advancements of hydrogel-based adsorbents as a green solution for their ease of use, ease of modification, biodegradability, non-toxicity, environmental friendliness, and cost-effectiveness. This study focuses on the design of an efficient adsorbent hydrogel based on 1% chitosan, 40% polyethylene glycol 4000 (PEG4000), and 4% xanthan gum (referred to as CPX) for the removal of diclofenac sodium (DCF) from water. The interaction between positively charged chitosan and negatively charged xanthan gum and PEG4000 leads to strengthening of the hydrogel structure. The obtained CPX hydrogel, prepared by a green, simple, easy, low-cost, and ecological method, has a higher viscosity due to the three-dimensional polymer network and mechanical stability. The physical, chemical, rheological, and pharmacotechnical parameters of the synthesized hydrogel were determined. Swelling analysis demonstrated that the new synthetized hydrogel is not pH-dependent. The obtained adsorbent hydrogel reached the adsorption capacity (172.41 mg/g) at the highest adsorbent amount (200 mg) after 350 min. In addition, the adsorption kinetics were calculated using a pseudo first-order model and Langmuir and Freundlich isotherm parameters. The results demonstrate that CPX hydrogel can be used as an efficient option to remove DCF as a pharmaceutical contaminant from wastewater.

“…Recently, advanced oxidation processes (Parra-Enciso et al, 2022), PMS activation (Zhao et al, 2022), bank filtration (de Carvalho Filho et al, 2022), and adsorption (Feng et al, 2022) have been conducted to remove diclofenac. Among them, adsorption is one of the most efficient, simple, nontoxic, and low-cost methods to remove pharmaceutical contaminants efficiently from the water environment.…”

In this work, polyaniline-coated carbon nanofiber with acid treatment (named CNFA@PANI) composite was synthesized and used to eliminate diclofenac from the water environment. Thanks to the abundant amino functional groups and benzene-ring structures, the as-prepared CNFA@PANI composite presented the excellent adsorption capacity (qe) of 202.9 mg/g and high distribution constant (Kd) value of 1.02×104 for diclofenac. The physical and chemical properties of the manufactured composites were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transformed infrared spectroscopy (FT-IR). The novel adsorbent possessed rapid and excellent adsorption performance for diclofenac. Moreover, in the wide pH range, the CNFA@PANI possessed well adsorption capacities. Meanwhile, after five adsorption-desorption cycles, the composite still showed excellent reusability performance. Furthermore, quantum chemical theory calculations indicated the possible adsorption sites of the composite for diclofenac. In total, this work provides an easy method to design novel composites for the efficient removal of diclofenac from the water environment.
