Özet:

 


For removal of Cu(II) ions from aqueous solution, a
novel composite was prepared from 1-vinyl imidazole and sepiolite by the
technique of in-situ polymerization. Adsorption of Cu(II) ions from aqueous solution onto Sepiolite-Poly(vinylimidazole) composite has been studied at 277,
298, 318, and 338 K and the experimental data were analyzed using fourteen
isotherm models. The determination
coefficients (R2) were determined for each
isotherm analysis. The determination
coefficients demonstrated
that in general the accuracy of models to fit experimental data improves with
the number of parameters. The Langmuir model provided the best fit to the
experimental data among the two-parameter isotherms. The Toth model provided
the best fit to the data among the three-parameter models. Adsorption isotherm
modeling shows that the interaction of Cu(II) with Sepiolite-Poly(vinylimidazole) composite surface is localized to
monolayer sorption and adsorption is an endothermic process. Additionally, adsorption
experiments showed that Sepiolite-Poly(vinylimidazole) composite
can be used as an effective adsorbent for the removal
of Cu(II) ions from aqueous solution.
