Isolation of Pectin from Carrot Peel as Biosorbent of Pb(II) ion

Abstract

Pectin is a promising bioadsorbents material for heavy metals' removal from aqueous solution. In this study, pectin was isolated from carrot peel by extraction method and evaluated as biosorbent for removal of toxic heavy metals (Pb(II)). The adsorption parameters for removal of Pb(II) were optimized, including pH, adsorbent mass, and contact time. The results shows that pectin can be isolated from carrot peel as was characterized by FT-IR spectra. The optimum condition for Pb(II) were at pH solution 6, Pb(II) with 44% removal capacity. The optimum adsobent mass was 15 mg with 46% removal capacity, whereas the optimum contact time was 120 min with 38% removal capacity.
