In this study, we prepared a magnetic composite based on amine-functionalized chitosan (aminochitosan; AmCS) and FeO to remove diclofenac sodium (DS) from water. The fabricated AmCS@FeO composite was characterized using Fourier-transform infrared spectroscopy, transmission electron microscopy, scanning electron microscopy, vibrating sample magnetometry, X-ray diffraction, and thermogravimetric analysis. Furthermore, we investigated the influence of pH, initial DS concentration, and adsorbent dosage on the adsorption of DS. Through thermodynamic analysis, we found that the data corresponded with the Langmuir adsorption isotherm model. The maximum adsorption capacity reached 469.48 mg g, and the adsorption process followed the pseudo-second-order kinetic model. Finally, the AmCS@FeO composite retained good adsorption characteristics after four consecutive cycles, with removal efficiency exceeding 70%. Therefore, the developed adsorbent could be used for efficient adsorptive removal of trace drugs and personal care products from water bodies.

The rise of various diseases demands the development of new agents with antioxidant, antimicrobial, anti-inflammatory, enzyme-inhibiting, and cytotoxic properties. In this study, heterocyclic Schiff base complexes of Cu(II) featuring a benzo[]thiophene moiety were synthesized and their biological activities evaluated. The complexes were characterized using FT-IR, UV-Vis, and EPR spectroscopy, TG-DTG analysis, magnetic moment measurements, molar conductivity measurements, and elemental analyses.

Diclofenac etalhyaluronate, an active pharmaceutical ingredient in JOYCLU (JCL), serves as a joint function improvement agent in knee and hip osteoarthritis patients. However, frequent cases of anaphylaxis induced by JCL administration have been reported. Recent clinical research suggests the potential utility of the basophil activation test (BAT) in predicting JCL-induced anaphylaxis.

This study examines pharmaceutical residues in the seawater of west Spitsbergen fjords, using indicator compounds that represent different types of medications with various therapeutic uses (sulfamethoxazole, trimethoprim, carbamazepine, diclofenac, and caffeine). Over three years (summer 2018-2021), trimethoprim, carbamazepine, diclofenac, and caffeine were detected in the investigated fjords (Hornsund, Adventfjorden, Grønnfjorden, Isfjorden, and Kongsfjorden), with diclofenac and caffeine being the most common. Sulfamethoxazole was below the limit of detection in all samples.

The widespread occurrence of new and emerging and persistent organic pollutants (NEPs and POPs) in surface water poses a risk to drinking water supply and consequently human health. The aim of this work was to investigate the occurrence and potential transport of 42 target NEPs and POPs (including per-and polyfluoroalkyl substances (PFAS), pharmaceuticals, pesticides and bisphenols) along the rural and urban environments of three rivers in England. The type and concentrations of pollutants varied between the sampling days and points.

Water is a fundamental component of life, playing a critical role in regulating metabolic processes and facilitating the dissolution and transport of essential molecules. However, emerging contaminants, such as pharmaceuticals, pose significant challenges to water quality and safety. Nanomaterial-based technologies emerge as a promising solution for removing those contaminants from water.
