Abstract
Reversible extraction of mineral acids and of their salts by acid-base couple extractants (mixed ionic solvents) provided the basis for several processes developed for the fertilizer industry and for treating industrial effluents. Extraction properties of couple extractants are strongly dependent on the acidity/basicity of their components. pH "SUB HN" values, (pH of half-neutralization) measured by contacting the extractant with HCl solution, were found to provide a convenient tool for tailoring extractant composition for various industrial uses.
