Various lignocellulosic waste materials were assessed for their potential usage as biosorbents Cd(II) removal from wastewaters.Sunflower seed shells, carrot peel, bean pods, eggplant and orange peel in dry form different grain sizes evaluated.Contact time, initial concentration, biosorbent amount also tested.Eggplant was the most efficient with an experimental biosorption capacity of 9.33 mg/g, a monolayer (Langmuir) 18.05 maximum % yield 97.33%.Experimental data best fitted Langmuir isotherm model (exception, peel) pseudo-second-order kinetic (all materials).
