Ultrasound-assisted abamectin removal using magnetic activated carbon from orange peel embedded in chitosan hydrogel beads.

ABSTRACT: Abamectin is a toxic environmental contaminant posing serious health risks; thus, its removal from water is essential. In this study, chitosan-based hydrogel beads containing varying amounts of magnetic activated carbon were synthesized and utilized for the removal of abamectin from wastewater. Characterization studies confirmed the successful preparation of the composites: FTIR spectra revealed functional groups and MAC-chitosan interactions, XRD confirmed the crystalline features, FESEM showed the uniform dispersion of MAC within the hydrogel matrix, and BET analysis demonstrated that the specific surface area of chitosan hydrogel beads increased from 28.61 m²/g to 43.86 m²/g after MAC incorporation. Batch adsorption studies showed that the chitosan-based hydrogel with 30% magnetic activ
