The recovery of Y(III) and Eu(III) from fluorescent lamp leachates via supported liquid membranes using Cyanex 923 as a carrier has been studied. The results reveal that the transport process is mainly controlled by the diffusion or the viscosity of the organic phase depending on the carrier concentrations. Furthermore, this paper compares the transport model for flat sheet supported liquid membranes and hollow fibre renewal liquid membranes regarding both REEs in nitrate media. The model allows foreseeing the permeability coefficients for these REEs as a function of the organic phase variables. This study reveals furthermore, that the difference on the permeability coefficients between both membranes correlates to their structural characteristics, e.g. tortuosity, thickness and porosity.

研究了使用Cyanex 923作为载体通过负载液膜从荧光灯浸出液中回收Y（III）和Eu（III）的方法。结果表明，取决于载体浓度，运输过程主要受有机相的扩散或粘度控制。此外，本文针对硝酸盐介质中的两种稀土元素，比较了平板支撑液膜和中空纤维更新液膜的传输模型。该模型可以预见这些稀土元素的渗透系数是有机相变量的函数。该研究进一步揭示，两个膜之间的渗透系数的差异与它们的结构特征相关，例如曲折度，厚度和孔隙率。
