Methionine-stevensite derived bionanocomposite: A green and efficient adsorbent for the removal of antibiotics
The persistent appearance of antibiotic residues in the aquatic ecosystem is considered an issue of great concern. This study examined the adsorptive efficiency of a novel bionanocomposite (L-methionine/stevensite, MET/ST) for promising decontamination of nine antibiotics. Results revealed that MET/...

This study examined the adsorptive efficiency of a novel bionanocomposite (L-methionine/stevensite, MET/ST) for promising decontamination of nine antibiotics. Results revealed that MET/ST allows an excellent antibiotic removal efficiency, from 87% for trimethoprim (TMP) to almost 100% for the eight remaining antibiotics, at neutral pH, an adsorbent dose of 2 g/L, and 1.5 mg/L of the antibiotics mixture. Equilibrium was achieved in less than 1 min, except for TMP (30 min), and the kinetics was consistent with the pseudo-second order model (R² > 0.927).

The high surface area (170.49 m²/g) and pore volume (0.16 cm³/g) of MET/ST, together with electrostatic and hydrogen bonding interactions, played a dominant role in antibiotic adsorption.
