Abstract
- Uptake of uranyl ions on polyacrylamidoxime resins synthesized from polymerization of acrylonitrile, and divinylbenzene as crosslinking agent in the presence of different diluents, then conversion of polyacrylonitrile to polyacrylamidoxime by hydroxylamine in basic media were investigated. FTIR on base polymer, functional resins, resins loaded with uranyl ions and that after elution were investigated. The effect of pore solvents on the morphologies of the prepared resins were examined by scanning electron microscope. Loading of uranyl ions performed with respect effects of pH, time of loading, and ratio of crosslinker. Elution of adsorbed ions carried out with different eluent and elution efficiency were determined. Regeneration of resins performed after six cycles and regeneration efficiency were determined.
