Cucumis melo rind as biosorbent to remove Fe(II) and Mn(II) from synthetic groundwater solution
Cucumis melo rind was evaluated as a new biosorbent for the removal of Fe(II) and Mn(II) from synthetic groundwater solution. The maximum sorption capacity of Fe(II) and Mn(II) was found to be 4.98 mg/g and 1.37 mg/g respectively. Sorption was most efficient at pH 7 and 6.5 for Fe(II) and Mn(II) res...

| Summary: | Cucumis melo rind was evaluated as a new biosorbent for the removal of Fe(II) and
Mn(II) from synthetic groundwater solution. The maximum sorption capacity of Fe(II) and Mn(II)
was found to be 4.98 mg/g and 1.37 mg/g respectively. Sorption was most efficient at pH 7 and 6.5
for Fe(II) and Mn(II) respectively. The biosorption of both metals increased as the quantity of
biosorbent increased. The increase in initial metal concentration was associated with steep increase
in biosorption at lower concentrations and progressively reaching towards plateau at higher metal
concentration. FTIR demonstrated that hydroxyl and carboxyl groups were involved in the
biosorption of the metal ions. The study points to the potential of new use of Cucumis melo rind as
an effective sorbent for the removal of Fe(II) and Mn(II) from aqueous solution. |
