AB  - Due to the tendency of spreading out of its natural habitat and posing a menace to the surrounding species
and biodiversity of the area under its influence, Acer negundo L. is known as the deciduous invasive tree
species. Even though it is considered harmful for ecosystems, the biomass of this invasive species can be
utilized for the purpose of wastewater remediation. A. negundo leaf biomass (AN) was investigated for its
adsorption potential to bind the lead ions from an aqueous solution. The lead was selected for the sorption
experiments, as it is a well-known pollutant often found in various industrial effluents. Acer negundo L. leaves
were collected from the protected area of the outstanding natural landscape “Veliko ratno Ostrvo” in Belgrade.
Experiments were carried out in a batch system under specific operational conditions. Precise amounts of
sorbent were added in the Pb (II) solutions of known initial concentrations, and the optimal operational
parameters were further evaluated. Parameters such as lead concentration, pH value, contact time, and
sorbent dosage were tested and optimized for increasing the adsorption performance of the obtained sorbent.
Maximum Pb (II) uptake occurred at pH 3,5 and sorbent dosage of 2 g/L. Very fast adsorption was noticed by
the kinetic study, with equilibrium state achieved after the initial 2 min of sorbent (A. negundo)-sorbate (1 mol/L
Pb (II) solution) contact. Obtained data were subjected to equilibrium modeling by using Langmuir and
Freundlich equations. Maximum adsorption capacity reached 101,5 mg/g. According to these results, sorbent
prepared from Acer negundo leaf powder has an outstanding potential to be applied for lead removal from
contaminated waters.
