In order to reveal the performance of Durian Leaves (DL) as a putatively advantageous
biosorbent for the removal of Pb(II) from aqueous solution, the kinetic of biosorption, and the
physio-chemical factors on biosorption were investigated comprehensively. DL was
characterized by using pHslurry and pHpzc of biosorbent. The effect of physicochemical such
as pH, adsorbent dosage, initial concentration of Pb(II) and contact time has been studied to
obtain the optimum condition to remove Pb(II) ion from the aqueous solution. The studies were
conducted at pH 4, DL dosage 0.04 g, and in contact time of 90 minutes. Kinetic data were
analyzed by using two adsorption kinetic models which are pseudo-first-order and pseudosecond-order. The data shows high correlation coefficient based on pseudo-second-order model
with R2
is 0.9905 rather than pseudo-first-order model. Our results demonstrate that the DL is
a promising biomass-based biosorbent for the removal of Pb(II) from wastewater for its fine
capacity of biosorption
