Effect of ionizing radiation on various zirconium phosphate derivatives

Zirconium phosphate (alpha-type), and zirconium phosphate-phosphite, and th eir silica containing forms were prepared. The products of syntheses and th eir purities and crystallinities were characterized by XRD diffraction. The reafter the samples were irradiated with gamma-rays (to 3 x 10(6) Gy absorb ed dose), after which irradiation the samples were again characterized. Com parison of the diffractograms reveals that irradiation does not result in d etectable structural changes. Thus, application of these materials as sorbe nts and as ion exchangers is suggested in processes taking place under irra diation. (C) 1999 Elsevier Science Ltd. All rights reserved.
