ABSTRACT:
Amine extractants useful in extracting metallic anions are modified with Lewis bases, having substantial organic solubility, such as tributyl phosphate, to improve the extraction capability of such amines. Generally, addition of Lewis bases to weakly basic amines increases the basicity of such amines.
