Removal of copper (II)‎ and ferric (III)‎ ions from aqueous solutions by adsorption using potato peel

Abstract EN

In this work, potato peel wastes were used as absorbents to remove heavy metals (Cu +2 and Fe +3 ) from aqueous solutions using adsorption method.

Effect of pH, contact time, adsorbent dosage and initial metal pollutants concentration was investigated.

Results showed that the adsorption of Cu and Fe ions increased with increasing pH of media and maximum adsorption of both cu and Fe was obtained around pH 5 - 6.

The maximum sorption capacity was found to be 39 and 28 mg/g for Cu+2 and Fe+3 , respectively.

Over all, the present findings suggest that potato peels are friendly environmental, efficient and low cost biosorbent which represents an excellent potential for Cu+2 and Fe +3 removals from aqueous solutions.
