Preparation of Malonamide−MCM-41 Materials for the Heterogeneous Extraction of Radionuclides

摘要: The grafting of malonamide-type molecules onto the surface mesoporous silicate MCM-41 in a two-step process is demonstrated. This synthesis route yields large concentration accessible extraction sites as high 2.5 μmol m-2. textural properties materials are shown to be preserved, demonstrated by XRD and TEM experiments. These new hybrid have been found separate americium(III) europium(III) from aqueous solution. regeneration these possible simply changing pH conditions. capabilities compare with those homogeneous-phase process.
