Nepal Chem. Soc.

FTIR studies were carried<br />out to understand the type of functional groups in unmodified and modified apple juice<br />residue responsible for metal binding process. Equilibrium adsorption data were fitted in<br />terms of monolayer adsorption at pH 4 by batch method. The kinetics was studied for<br />biosorption processes and data were described by pseudo second order model. The<br />equilibrium constant and Gibbs free energy of the adsorption at 25&deg;C were determined. The<br />mechanism of sorption was found to obey the ion exchange and complexation method.</p><p><em><strong>Keywords:</strong></em> Heavy metal; Biosorption; Xanthate; Iion exchange; Complexation</p><p>DOI: 10.3126/jncs.v26i0.3632</p><p><em><strong>Journal of Nepal Chemical Society</strong></em><br />Vol. 26, 2010<br />Page: 53-60</p> ER -
