摘要：

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