The objective of the study was to assess the usefulness of the Transcarpatien zeolite-clinoptylolite ( Sokirnica,Ukraine) when applied to the removal of Hg(II),Ni(II) and Cr(III) ions from aqueous solutions.The experiments were carried out with three types of clinoptylolite samples-natural,after thermal processing ( 300 and 500.o C),and after chemical modification (with NH4Cl or HCl).Thus,natural clinoptylolote adr clinoptylolite modifical with 3N NH4Cl were found to have a high sorbing capacity.Maximum adsorption of Hg(II) ions (amounting to 4.7 mg/g was achieved within two hours.The adsorption of Ni(II) ions was alamost complete wilin on hour.The efficiency of Cr(III), ion adsorption amounted to 70%. These data indicate that the investigated clynoptilolite has a potential for being effectively used in water treatment for drunking purposes.Ist properties make in also applicable to the removal of heavy metals from wasterwater. A low initial concentrations of Ni(II) and Cr(III), a good treatment effect conbe achieved within a comparatively short time of contact,ar a result of filtration on the clinoptylolite bed.
