摘要：
A process of acetylosalicylic acid removal from aqueous solution by emulsion liquid membrane has been investigated. Effects of process parameters (rotation speed, volume ratios of phases, total volume of phases and NaOH concentration in the inner phase) on the removal rate have been examined. The model of batch extraction with double emulsion presented by KIM et al. [10] has been modified by addition of an interfacial resistance for mass transfer. The model has been solved by perturbation method. The experimental results are in good agreement with those predicted by the model.
