Abstract
The silica layer protected magnetite (Fe3O4) NPs were functionalized with phosphate group bearing monomer ethylene glycol methacrylate phosphate (EGMP) and its polymer (poly(EGMP) having affinity toward f-element ions. The polymerizable double bonds of EGMP anchored on silica coated magnetite NPs were used to grow poly(EGMP) chains by γ-rays induced polymerization. It was observed in the extraction studies that Pu4+ ions sorbed preferentially in Fe3O4@SiO2-EGMP NPs over UO22+ ions from 3 mol L−1 HNO3. Contrary to this, Fe3O4@SiO2-poly(EGMP) NPs did not exhibit significant selectivity toward UO22+ and Pu4+ ions under similar chemical conditions. Indicating a multiple ligating groups coordination requirement for the binding of UO22+ ions with phosphate groups.
