Abstract
En 中文
The increasing occurrence of active pharmaceutical ingredients (APIs) in aquatic environments poses risks to ecosystems and human health, underscoring the necessity for effective removal strategies. This study involved the synthesis of manganese ferrite (MnFe2O₄) nanoparticles (MFO-NPs) through a controlled co-precipitation method and characterized X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and Brunauer–Emmett–Teller surface area analysis. The adsorptive performance of MFO-NPs has been evaluated for the removal of quetiapine and lansoprazole as APIs from an aquatic environment under varying operational parameters, including pH, MFO-NP dosage, calcination temperature, contact time, and initial API concentration. Kinetic, isotherm, and thermodynamic modeling studies were also performed to clarify the adsorption behavior. Additionally, binary adsorption trials of lansoprazole and quetiapine, as well as regeneration experiments, have been performed.
