中文摘要	the inner synergistic extraction of [tricaprylmethylammonium][sec-octylphenoxy acetate] ([a336][ca-12]) is studied for cobalt and nickel separation. distribution ratios of [a336][ca-12] for co2+ or ni2+ are by far higher than those of tricaprylmethylammonium sulfate ([a336](2)so4), sec-octylphenoxy acetic acid (ca-12), mixture of [a336](2)so4 and ca-12 at the acidities from 1 x 10(-5) mol l-1 to 1 x 10(-3) mol l-1. the synergy coefficients of [a336][ca-12] for co2+ are higher than the synergy coefficients of [a336][ca-12] for ni2+, which can be used for the co2+ and ni2+ separation. some thermodynamic properties of the inner synergistic extraction using [a336][ca-12] for co2+ and ni2+ are also studied, such as influence of temperature, thermodynamic functions, extraction mechanism, separation factors and stripping properties.
