Description

Method of residual concentrations, measurement of electric conductivity and pH, differential thermal, X-ray phase and chemical analyses, infrared spectroscopy were used for investigation of praseodymium (3) chloride interaction with sodium decavanadate in aqueous solution. It was established that 25-aqueous praseodymium decavanadate Pr2V10O28 X 25H2O formed as the intermediate solid phase. Then it transformed to the stable solid phase - hexahydrate of acid praseodymium pyrovanadate PrHV2O7 X 6H2O. The prepared vanadates decomposed at ∼ 130-160 deg C with formation of praseodymium orthovanadate and vanadium (5) oxide
