Investigations on the silica gel supported form of microcrystalline zirconium phosphate ion exchanger and its applications in chemical separations

The ion exchanger Si-ZrP in the form of particles of high mechanical stability and good ion exchange performance was prepared by precipitating silicic acid in the slurry of crystalline zirconium phosphate. The conditions of preparation were optimally chosen. The stability of Si-ZrP ion exchanger particles in acidic and basic solutions, the ion exchange properties and kinetics of Si-ZrP were investigated.
