Abstract
Experiments dealing with the effects of TOA concentrations on time cou rses of chromium molar fractions in the external, organic and internal phases during the separation-concentration process of chromium were c arried out using Span 80 and two kinds of polyamine surfactants, Polya mine-E and Polyamine-L. The optimum TOA concentration and the optimum extraction time were determined in order to obtain the maximum chromiu m molar fraction in the internal phase.
