The basic adsorption performance of metastannic acid (H2SnO3) was evaluated in an extraction chromatography method for the selective removal of Mo(VI) and Sb(III) from MA products in the MA(III) and Ln(III) co-recovery process. The results of this study indicate that metastannic acid can separate Mo(VI) and Sb(III) at a nitric acid concentration of 0.1 M.
