ABSTRACT

fabric was treated with a reactive anionic agent in order to have anionic sites(-SO3-) on it, which made it possible for the fabric to adsorb various cationic materials.In this study, the adsorptivity of various heavy metal ions such as Pb(Ⅱ), Cd(Ⅱ), Cr(Ⅲ), Co(Ⅱ), Cu(Ⅱ), Ni(Ⅱ) and Cr(Ⅵ) on the cotton fabrics treated with anionic agent was examined at the various conditions; concentrations of heavy metal ions, pHs of solution, reaction time and temperature. As a result, the adsorptivity of the heavy metal ions on the cotton fabrics treated with the anionic agent was highly increased comparing to that of untreated cotton fabrics. The order of the adsorptivity was as follows : Pb(Ⅱ)>Cd(Ⅱ)>Cu(Ⅱ)≥Ni(Ⅱ)≥Co(Ⅱ)>Cr(Ⅲ)≫Cr(Ⅵ). The adsorption amounts of most heavy metal ions were increased in weak alkaline conditions and were reached to an adsorption equilibrium within 10~30 minutes. The maximum adsorption ratios of Pb(Ⅱ) and Cd(Ⅱ) were respectively 99% and 80% of the initial concentration of heavy metal ions.Therefore the anionized cotton fabrics seem to be utilized as an adsorption fabrics for the removal of heavy metal ions in the waste water.
