UPTAKE OF Ni, Pb AND Zn FROM AQUEOUS SOLUTION BY ADSORPTION USING PETIOLAR FELT-SHEATH OF PALM
Abstract
Adsorption studies of Ni. Pb** and Zn" from aqueous solution on dried biomass of petiolar felt-sheath of palm (PFP) are reported. PFP was found to efficiently remove all the toxic metal ions from for sHaueue solution in high gict. The maximum soprian cepacity of the PEP biomass at squirium " Pb" and Zn" was 79.50, 96.17 and 80.64%, respectively. The general binding efficiency indicated a selectivity order of Pb*>Zn*>Ni. The uptake was rapid, with more than 70% completed within 15 min. After the adsorption, the metal ions retained in the PFP biomass were recovered by cluting with 0.1 M HCl and PFP biomass was successfully reused
