Abstract

AbstractThe methods for producing bismuth pentahydrate from metallic bismuth by the interaction of oxide or basic bismuth nitrate with solutions of nitric acid were compared using X-ray phase, chemical, atomic absorption, mass spectrometric analyses, and electron microscopy. The possibility of preparing it from bismuth metal as a result of oxidation of the latter and processing of the produced oxide with a solution of nitric acid is shown. A variant of the preparation of bismuth pentahydrate is considered by preliminary hydrolytic purification of bismuth-containing nitric acid solutions by precipitation of bismuth in the form of oxohydroxonitrate and its interaction with nitric acid solutions. A technology has been developed to eliminate the emission of toxic nitrogen oxides into the atmosphere and to produce high purity bismuth pentahydrate.
