Adsorption behaviour of copper (II) ion from aqueous solution on poly(4-vinyl pyridine)

The adsorption behaviour of poly(4 - vinyl pyridine) towards copper (II) ion in aqueous solutions was studied by a batch equilibriation technique. Influence of treatment lime, pH of the solution and metal ion concentration on the adsorption were investigated. 45 minutes of adsorption time was found...

Zusammenfassung:	The adsorption behaviour of poly(4 - vinyl pyridine) towards copper (II) ion in aqueous solutions was studied by a batch equilibriation technique. Influence of treatment lime, pH of the solution and metal ion concentration on the adsorption were investigated. 45 minutes of adsorption time was found sufficient to reach adsorption equilibrum for the copper (II) ion. The optimum pH was found to be 4,5. The adsorption saturation value was reached at 1,27 mmol ions per gram poly(4 - vinyl pyridine) against 3.15 mM copper (II) ions. It was observed that the adsorption isotherm of Cu (II) fits Freundlich - type isotherms.
