Biosorption of Nickel Ions by Modified Chitosan from Aqueous Solutions

Article Preview

Abstract:

Since commercial chitosan powder may dissolve in water to some degree and demands to be modified chemically to create its own exclusive pore canal we have synthetized two different modified chitosan beads in this investigation by using glutaraldehyde as crosslinking agent, significantly, novel porogen silica sol and methanol, and analysis means SEM, FTIR and BET demonstrated that the surface area and pore size improved signally. Moreover, the adsorption conditions pH and ionic strength have been considered, and the maximum adsorption capacity of nickel ions was 32.40 mg/g at the optimum condition. Furthermore, the main model equations on isotherm and kinetics have been deliberated and the results clearly revealed that Freundlich, external mass transfer, intra particle diffusion and pseudo second order model fitted better to the experimental data (R2 > 0.99, all). It is expected that this results would be serviceable to remove metals from wastewater using chitosan and its derivatives.
