Extractants

"SOLVEX" company has developed and patented new extractants Sulfoxon and Fluoroamine BSA-21 for SX, separation and purification of noble and non-ferrous metals.

Distinctive features in comparison with Alamine® 336:

  • High stability to the oxidants (oxygen, nitric acid, hydrogen peroxide)
  • Efficient extraction of metals from the acidic solutions (does not form salts with HCl, HNO3, H2SO4 at pH > 1)
  • Low solubility in water
  • Moderate extractive capacity, higher selectivity and easier stripping
  • The possibility of using as an additive to other extractants
  • Low viscosity
