Description 412-420
Green synthesis of bentonite-iron nanoparticles (Be-FeNPs) has been carried out using the leaf extract of Helicteres
isora and its antibacterial and adsorption capacity for the removal of Methyl Blue (MB) dye have been also studied.T he
prepared Be-FeNPs and iron nanoparticles (FeNPs) are characterized by UV-visible, FTIR spectroscopic techniques and
SEM analysis. The antibacterial activity of Be-FeNPs show good zone of inhibition against E.coli and S.aureus. Further the
prepared composite (Be-FeNPs) and bentonite are used as adsorbents for the removal of Methyl Blue (MB) dye in aqueous
solution under various experiment parameters like initial concentration, contact time and pH. The optimum initial pH,
adsorbent concentration and time were determined to be 8.1, 45°C, and 100 ppm, 80 min for MB adsorption on to
Be-FeNPs. The experimental data for MB adsorption fits well to the Freundlich and Langmuir isotherm models. The kinetic
equations like Natarajan-Khalaf, Bhattacharya-Venkobachar and Lagergren equations were found to be applicable. The
surface morphology of the Be-FeNPs before and after adsorption of dye revealed that it can be used as an excellent
adsorbent for dye removal from dilute industrial effluents.
