| Abstract: | The physicochemical modeling of the behavior of impurities in the course of their preconcentration by the chemical distillation
of the sample matrix consisting of granules of a solid solution of impurities in bismuth oxide was carried out. It was supposed
that the distillation process is conducted in a kinetic mode. The results of calculations by the model are compared with the
earlier results of modeling of the behavior of impurities in distilling a heterophase sample consisting of matrix (bismuth
oxide) granules and granules of impurity oxides. The experimental data and results of calculations by the model agree well. |
