Preparation of a novel nanocomposite for removal of Cs+ and Sr2+ from aqueous solutions

Phenolsulphonic formaldehyde resin - potassium nickel hexacynoferrate - clinoptilolite nanocomposite wasprepared by incorporating potassium nickel hexacyanoferrate in the porous matrix of nano sized zeolite by successiveimpregnation with Ni(NO3)2 and K4Fe(CN)6. Phenolsulphonic-formaldehyde resins were used to prepare compositeion-exchangers in the form of spherical beads . The sample was characterized by fourier transform infraredspectroscopy (FT-IR). The composite beads were used for removal of Cs+ and Sr2+ from aqueous solutions. The effectof different variables such as pH and initial concentration was studied and optimized.
