Abstract
Hexacyanoferrates (HCFs) are known to be efficient sorbents for the removal of Cs from aqueous solutions. But the powdery precipitate of HCF is unsuit able for use in columns. To make it amenable to column application, it has been coated on polyacrylic fibres by in situ precipitation. In batch and co lumn experiments, the fibres coated with Cupric ferric hexacyanoferrate pro vided good removal of Cs-137 from radioactive effluents. Leaching of Cs fro m the fibres was found to be only 14% in demineralised water medium. The Cs -loaded fibres could easily be incinerated to a smaller volume for further conditioning.
