Summary: The study demonstrated that PAC@Fe3O4-MN exhibited excellent adsorption capacity for CIP, with a favorable, spontaneous, and endothermic process. The interaction of CIP with PAC@Fe3O4-MN was found to occur through both chemical and physical reactions on a homogeneous layer of active sites, controlled by film diffusion. The adsorbent showed promise for sustainable and cost-effective treatment of CIP-contaminated wastewater, with the ability to be recycled through multiple adsorption-desorption cycles.

Summary: Antibiotics pose a growing environmental challenge due to their mutagenic and persistent effects. In this study, y-Fe2O3 and ferrites nanocomposites co-modified carbon nanotubes were synthesized for the removal of ciprofloxacin. The adsorption capacities of ciprofloxacin on y-Fe2O3/MFe2O4/CNTs were determined to be 44.54 (Co), 41.13 (Cu), and 41.53 (Mn) mg/g. The adsorption mechanisms were explored and the role of magnetic substances in the adsorption process was revealed. This research provides insights for the development of similar adsorbents for environmental applications.

Summary: This study developed a highly efficient and low-cost activated carbon (BAC-600) derived from bagasse, which was used for the removal of sulfamethoxazole (SMZ) from water. The adsorption conditions were optimized using response surface methodology (RSM) with a Box-Behnken design (BBD). BAC-600 exhibited excellent adsorption performance, fitting well with the pseudo-second-order model. The adsorption mechanism of SMZ on BAC-600 involved hydrogen bonding, electrostatic interaction, and p-p interaction. This research provides a potential solution for eliminating environmental pollution caused by antibiotics in water.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
