文摘
- •
A green method on extracting tungsten was proposed by aqueous two-phase system.
- •
The results indicate that aqueous pH is the main factor on tungsten extraction.
- •
The solubilization capacity of tungsten is independent of temperature.
- •
Polytungstate anion is solubilized in hydrophilic shell of Triton X-100 micelles.
- •
The stripping of tungsten is mainly influenced by temperature and achieves 95%.
