Abstract
The water quality is being degraded due to disposal of the industrial effluents without prior
treatment into the water bodies. It is dire need to treat the effluents with cost effective and
environment friendly adsorbents. The present study aims to evaluate the batch scale adsorption
potential of previously unexplored corn leaves (CL) and its nanocomposites with zinc oxide
(CL/ZnO) and magnetite nanoparticles (CL/MNPs) for the removal of Brilliant green dye (BG).
The effects of adsorbent dose (1 – 4 g/L), initial concentration (25 - 200 mg/L) of BG, solution
pH (2 - 8), and contact time (15 - 180 min) were evaluated to remove BG from contaminated
water. The results show that the removal of BG was 94-84%, 99-94% and 94-88% and 8-5%
with CL, CL/ZnO, and CL/MNPs when the initial BG was changed from 25-200 mg/L at
ambient temperature. Moreover, the experimental data was validated with kinetic and
nd
equilibrium models. Freundlich model was best suited for equilibrium study, while pseudo 2
2
order was well explained the kinetic adsorption data (R =0.99). Based on the current findings,
it is suggested test the composites of nanoparticles with biosorbents for the remediation of BG
and other contaminants at industrial level.
