Abstract

Ability to remove Pb (II) from aqueous solution by Durian leaves (DL) was
evaluated. DL was characterized by using pHslurry and pHzpc 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, DLP dosage 0.02 g,
in contact time of 90 minutes. Kinetic data were analyzed by using two adsorption
kinetic model which is pseudo-first-order and pseudo-second-order. The data shows
high correlation coefficient based on pseudo-second-order model with R2 is 0.9966
rather than pseudo-first-order model.
