Abstract

Ionic state of Re(VII), Mo(VI), V(V) and W(VI) ions in mineral acid solutions has been studied using “Fixion-50” cationite fixed layers depending on nature of acids, their concentration and activation of ionite layers. The ranges of acidity and concentration where ions exist in the definite ionic state were specified by using ion-exchange thin-layer chromatography method. It has been shown that the indicated version of chromatography has some advantages in comparison with column ion-exchange chromatography method – expressness of carrying out experiments, simple instrumental requirements, reproducibility, reliability and accuracy of results. New methods for separation of above mentioned elements’ mixtures have been elaborated.
