The biosorptive potentials of Ageratum conyzoides leaves powder as biosorbents, were evaluated, for the first time for Pb(II) removal from aqueous solutions. The influence of biosorbent size (53-152 µm), agitation times (1-180min), pH from 2 to 8, initial concentrations of lead in aqueous solution with (50-200 mg/L), Ageratum conyzoides leaves powder dose (0.25-3.0g), temperatures (283-323 K), were investigated. The maximum sorption capacities of Pb(II) ions onto Ageratum conyzoides leaf powder was (89.1697 %).The kinetic data modeling resulted in good correlations with the pseudo-second (R2= 0.9965) order.Thermodynamic parameters indicated the spontaneity and endothermic nature of lead biosorption on Ageratum conyzoides leaf powder biomass and the sorption capacities were in good agreement with the uptake capacity of Langmuir model.
