| Summary: | <p>A batch adsorption system was applied to study the adsorption Cu(II) ions from aqueous solution by chitosan<br />
and nanomagnetic chitosan. In this work, nanomagnetic chitosan was fabricated by the covalent binding of<br />
carboxymetylchitosan on Fe3O4 nanoparticle via carbodiimade activation. From the increased weight after chitosan<br />
binding and the OPA method, the amount of chitosan bound on nanoparticle was estimated to the about 4.89 %wt<br />
Experiments were carried out of function of pH, agitation period and concentration of Cu(II) ion. The adsorption<br />
capacities and rate Cu(II) ion onto chitosan and nanomagnetic chitosan were evaluated. Compared with chitosan,<br />
the adsorption equilibrium of the adsorption capacities highly increased, the equilibrium could be achieved in one<br />
minute, and the maximum adsorption capacities could reach 428 mg/g, while only 200 mg/g using about 60 minutes<br />
to reach equilibrium for the chitosan.</p> |
