Abstract :
The interaction of solid basic bismuth nitrate (BBN) with citric acid solutions is studied. The formation of bismuth citrate of the type BiC6H5O7 occurs in the temperature range 50-70degC at pH 0.5-0.7. The obtained product is characterized by the methods of chemical analysis, X-ray powder diffraction, IR spectroscopy and differentional thermal analysis. The method of synthesis of bismuth citrate BiC6H5O7 by the solid-liquid reaction is compared with the precipitate method from nitric acid solutions.
