In the extraction of cobalt and nickel from an aqueous solution containing both metals and using di-(2-ethylhexyl)phosphoric acid (HDEHP) and 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester (EHPNA), interaction occurs which influences the amount of each of the metals extracted. For ideal conditions where only monomeric metal species is extracted, an
