Summary:A process for realizing the extraction-back extraction at same class by use of the hollow fibers updating liquid film technique features that the affinity between hollow fiber membrane and solvent phase is used to generate a very-thin solvent phase film on the one surface of hollow fiber membrane and the solute is selectively migrated between material phase and back extraction phase. Its advantages are high mass transfer efficiency, and high speed and selectivity for separating or concentrating solute.
