Abstract

The kinetics of dissolution and methods of phase analysis of antimony compounds have been studied repeatedly. To study the kinetics of Sb₂S₃ and Sb₂O₃ dissolution in KOH solutions, polydisperse samples of these antimony compounds (analytical grade) were taken with a view to using them for phase analysis. Using the low temperature inert gas adsorption method, the specific surface area was determined for Sb₂S₃ and Sb₂O₃. The kinetics of the interaction of Sb₂O₃ with solutions follows the laws of first order reactions under the conditions of the diffusion regime of the dissolution process. The dissolution of Sb₂O₃ and Sb₂S₃ in solutions cannot be used for selective dissolution in phase analysis. ...
