The effective removal of heavy metals from aqueous solutions is the most important issues for many countries. Removal of lead(II), zinc(II) and cadmium(II) from aqueous solutions were studied using Tobacco leaves. Batch sorption experiments were performed as a function of pH, contact time, solute concentration, temperature, particle size and sorbent dose. The maximum contact time for the equilibrium condition was 120min at the sorbent dose rate of 0.5g. The results were well fitted by both Langmuir and Freundlich isotherm models.
