Studies on a new composites material polyanilinezirconium(IV) tungstophosphate -a thorium(IV) selective cation exchanger

Department of Applied Chemistry & Polymer Technology, Delhi College of Engineering, Bawana Road, Delhi- 11 0 042, India Manuscript received 6 September 2001. revised 25 January 2002, accepted 27 August 2002 A new composite ion exchanger polyanilinezirconium(lV) tungstophosphate has been synthesized with the precipitation of zirconium tungstophosphate gel followed by polymerization of aniline in the presence of ammonium persulfate (APS). Its ion exchange capacities, ESCA, TGA, DTA, IR, X-ray, pH titrations, distribution behavior have been reported. Its utility has been explored by achieving the separation of LaIII from ThIV
