摘要：

The transport of manganese and cobalt ions from sulphate solutions through a supported liquid membrane containing DP-8R (acidic extractant) dissolved in Exxsol D 100 as a mobile carrier was investigated at 20 degreesC. The transport system was studied as a function of several variables: stirring speed of the source and receiving phases, concentration of the strippant in the receiving phase, pH of the source phase, diluent of the membrane phase and extractant and metal concentrations in the membrane and source phases, respectively. Higher selectivity in the separation of manganese and cobalt was obtained when the source phase presented higher [Co]/[Mn] concentration ratios. (C) 2002 Elsevier Science B.V. All rights reserved.
