Honeybee chitosan was used as a fine powder for sorption of heavy metals (e.g. Pb(ll), Cd(II) and Cu(II)). The heavy metals contents in filtrate after sorption have been determined by atom absorption spectroscopic method. Adsorption experiments were carried out as a function of pH. Chitosan possesses the highest sorption ability towards Pb(II) ions in weakly acidic medium in comparison with other metals. As follows from obtained data Cd(II) and Cu(II) is not sorbed by chitosan in strong acid medium. The maximum heavy metals sorption occurred at 2 hours of shaking. For Cu(II) ions the sorption kinetic was determined by UV spectroscopy. These results show that chitosan from honeybee as readily available economic sorbent is suitable for removing of heavy metals.
