POLYNITROGEN REAGENTS IN METAL SEPARATION. PART 1. DITERTIARY AND DIQUATERNARY AMMONIUM EXTRACTANTS FOR COBALT(II) AND COPPER(II) IN HCl MEDIUM.

Abstract
A variety of alkyldiammonium extractants (tertiary and quaternary)were prepared, characterised and used to extract cobalt(II) and copper(II) from HCl medium. These extractants were compared with Aliquat-336 and Alamine-336. The diammonium derivatives of ethylene diamine proved to be superior to their mono analogues.
