Abstract

The extraction of BPA (Bisphenol A) from aqueous solutions was performed using A set of three-dimensional spiral plate-type microchannel (3D-SPM) by emulsion liquid membrane (ELM). In the continuous extraction experiments, the effect of the flow rate ratio of emulsion to external aqueous phase ratios, Qe/Qa and height of microchannel, H and plate numbers, P, on the BPA extraction was studied. It was found that the less the height of microchannel is, the more extraction efficient it is. By increasing the plate number, the extraction efficiency and the distribution coefficient increase. The optimum performance was investigated by changing the flow rates of Qa and Qe. When using the flow rate ratio Qe/Qa of 7:1 in a 3D-SPM with a plate number of 9 and a height of 100 µm, 97% maximum depletion of BPA was obtained in 7.9 Seconds. These results show that 3D-SPM can intensify the ELM extraction process of BPA, which provides an optional technology for the disposal of BPA.
