dc.description.abstract | 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/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 isotherm data were fitted with the Langmuir and Freundlich models (R² > 0.960) (qmax from 21.48 to 28168 mg/g for TMP and chlortetracycline, respectively). 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. TMP was the only antibiotic affected by temperature (from 61% to 85% at 5 and 45ºC) and salinity (from 87% to 37% at 0 and 4% w/v of NaCl). The MET/ST was used consecutively for at least four adsorption–desorption cycles after being regenerated with a capacity > 97% in the last cycle for 7 out of 9 antibiotics. In addition to its adsorption capacity, reusability and low-cost features, the material demonstrated an excellent efficiency (up to 69% for TMP and 100% for other antibiotics) in wastewater and surface water samples denoting a great application for water purification. | es |
