Abstract
The interaction of solid bismuth oxohydroxonitrates having the composition [Bi6O4(OH)4](NO3)6 x 4H2O (I), [Bi6O5(OH3)](NO3)5 x 3H2O (II) and [Bi6O4(OH)4](NO3)6 x H2O (III) with the aqueous solutions of citric acid was studied by means of X-ray phase analysis, electron microscopy and atomic emission spectroscopy. The conditions for the formation of bismuth citrate having the composition BiC6H5O7 were determined.
