Synthesis and characterization of iodovanadinite using PdI_2, an iodine source for the immobilisation of radioiodine.

ABSTRACT: The synthesis of a palladium-containing iodovanadinite derivative, hypothetically "PdPb₉(VO₄)₆I₂", was attempted using PdI₂ as a source of iodine in searching for a novel waste form for radioiodine. Stoichiometric amounts of Pb₃(VO₄)₂ and PdI₂ were batched and reacted at elevated temperatures in sealed vessels. Batched material was also subjected to high-energy ball-milling (HEBM) in order to reduce reaction time and the potential for iodine volatilization during subsequent reaction at 200-500 °C. The resulting products were characterized using X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray analysis, IR spectroscopy, thermal analysis and Pd K XANES. Results showed th
