Mutual separation of (W, As, Mo, V, Ge, B) oxoanions from bi-metallic solution by resin having methyl-amino-glucitol moiety

The mutual separation of (W, As, Mo, V, Ge, B)-oxoanions using resin having methyl-amino-glucitol polymeric moiety from bimetallic solution was investigated by means of dynamic column experiments. The effect of solution pH on the separation efficiency and on the co-removal level of metallic impurities was followed in this study. The conditions for efficient desorption of metals were determined in order to get the highly concentrated, impurities free solution suitable for recovery and reuse of separated metal. Effective separation of molybdenum and vanadium from boron or germanium and tungsten from arsenic was achieved.
