Abstract

An attempt was made to redefine a commonly used parameter for steric effects, n, to reflect the steric effects of the ligand substituents in complexes formed in separation of Co(II) and Ni(II) by mono-basic alkylphosphonates and phosphates.

Key words: COBALT, NICKEL, EXTRACTIVE AGENT, SOLVENT EXTRACTION, EQUILIBRIUM CONSTANT, PARAMETER, PHOSPHORIC ACID ESTER, STERIC EFFECT, SUBSTITUENT EFFECT, ETHYLHEXYL PHOSPHONIC ACID MONOETHYL HEXYLESTER
