A new preparation method for the synthesis of TiO2 microrods is based on the extraction of sulfate ions from the crystals of titanyl sulfate dihydrate in aqueous ammonia solution leaving the Ti−O framework intact. The resulting metatitanic acid possesses excellent sorption properties toward radionuclides, and transforms to TiO2 upon heating. The morphology of particles remains unchanged during the whole process.
