Sheep wool water-washed in ultrasonic bath and slightly pre-dried was irradiated by accelerated electron beam applying dose of (0-350) kGy. The samples underwent sorption examination with Cr(III), Cd(II) and Pb(II). Sorption of Cr(III) by the irradiated wool investigated at unified concentration of 24 mmol dm(-3) for each absorbed dose showed intensive increase of Cr(III) sorption up to 3.13 x against the non-irradiated sample. It is concluded that some residual humidity in irradiated wool, being a rich oxygen source, enhances sorption due to faster cysteic acid formation. Sorption experiments with Cr(III), Cd(II) and Pb(II) ions of lower concentration up to 1.4 mmol dm(-3) individually indicated equal sorption as for non-irradiated wool up to 0.4 mmol dm(-3). Beyond this concentration the sorption for the non-irradiated wool was lower compared with irradiated wool for any dose. The sorption increase depending on dose was different for particular doses. The order of the sorption in mg ion/1 g wool is in conformity with published data and correlates with size of the ionic radii (Pb(II) > Cd (II) > Gr(III)).
