carrier liquid
6.The experimental results in detail is as follows:(1) Emulsion liquid membrane separationFirstly, the transport rate of Cr(VI) through ELM used TBP as the mobile carrier and Span80 as the surfactant, was studied by the Emulsion liquid membrane system. The effects of various parameters, such as the pH values in external water phase, the concentration of NaOH in inner water phase, carrier concentration, surfactant concentration, the Roi values and Rew, values were investigated;
