Abstract

The biosorption properties of the Cucumis melo (Cmelo) rind to remove Fe and Pb ions from groundwater solutions were investigated. The effect of different metal optimized conditions (contact time, biosorbent dosage and pH) on metal uptake by C.melo were investigated and metal removal were up to 96.83% for Fe and 94.88% for Pb ion under Fe ion optimized conditions. While under Pb ions optimized conditions, the removal percentage obtained were up to 87.19% for Fe and 95.09 for Pb ion after 45 minutes agitation in lOOml of groundwater samples with biosorbent dosage of 0.05 g. Adsorption isotherm analysis data of both metal ions were fitted well to the Langmuir model with maximum adsorption capacity of 5.3505mglg and 0.0830 mg/g for Fe and Pb ions respectively. The kinetic experimental data correlated well with the pseudo-second order kinetics model. From the characterization study of the biosorbent using SEM-EDX, FTIR and XRF, ion exchange and micro precipitation were estimated to be the main mechanism governing the biosorption process by Cmelo rind. The results demonstrated that C.melo rind has potential to be developed as the adsorbent material for the removal of Fe and Pb ions from groundwater
