M. Iqbal et al., Petiolar felt-sheath of palm: a new biosorbent for the removal of heavy metals from contaminated water, BIORES TECH, 81(2), 2002, pp. 151-153
Biosorption of heavy metals such as Pb2+, Ni2+, Cd2+, Cu2+, Cr3+ and Zn2- b
y petiolar felt-sheath of palm (PFP) from contaminated water was examined.
PFP was found to efficiently remove all the toxic metal ions with selectivi
ty order of Pb2+ > Cd2+ > Cu2+ > Zn2+ > Ni2+ > Cr3+. The uptake was rapid,
with more than 70% completed within 15 min. The bound metal ions were succe
ssfully desorbed and the PFP fibrous-biomass remained effective after sever
al adsorption-desorption cycles. (C) 2001 Elsevier Science Ltd. All rights
