Adsorption of hazardous ions from radioactive waste on chelating cloth filter

A cloth filter was synthesized by grafting of acrylonitrile/methacylic acid (AN/MAA ≈80%/20% molar ratio) onto cotton cloth using a radiation-induced technique followed by amidoximation reaction. The fate of adsorption of radionuclide (e.g. U(VI)) on chelating cloth filter (CCF) from radioactive waste was investigated. The adsorption ability of the CCF increases as pH increases from 6 to 10. The predominant composition of the resulting complex was determined. A chemical adsorption mechanism was confirmed by examining the relationships between the adsorbed amount of radionuclide and the contact time.
