摘要：
The diagrams of C-x/C-o-pH with W-H2O and Mo-H2O systems were established, separately, through thermodynamic analysis. Based on the different conditions to form polymeric anions of both metals, the optimum solution pH for the separation of tungsten from molybdenum was determined in the range of 7.5-8.0.A weak basic resin D363 was selected to selectively adsorb the polymerised W7O246- species for the removal of tungsten from molybdate solutions, which has validated the thermodynamic analysis results.
