研究将铁磁性颗粒应用于乳状液膜(ELM),提出了一种关于乳状液膜的新的操作方式。考查了含D2EHPH的磁性油和油包水(W/O)乳滴自位于磁场中的喷柱中从水溶液里提取锌的情况,包括液滴的运动特征。对W/O液滴通过设置永久磁铁从外水相中分离出分散相,使整个操作更加柔和。在旋转磁场和交变磁场中磁性液滴的运动特性取决于磁场强度。对油包水(W/O)液滴,能被稳在磁场中并形成一种拥挤的流动床,由此可显著提高提取率,尤其是在逆流操作中,可提高相间的有效接触,据此建议使用磁性W/O液滴的运动床和喷柱的混合操作。
The application of ferromagnetic particles to emulsion liquid membranes (ELMs) proposed a new mode of operation for emulsion liquid membranes. Examined the case of D2EHPH-containing magnetic oil and water-in-oil (W / O) droplets extracting zinc from an aqueous solution from a jet positioned in a magnetic field, including the movement characteristics of the droplets. The W / O droplet is separated from the external aqueous phase by setting a permanent magnet to disperse the dispersed phase, making the overall operation more gentle. The magnetic properties of the droplets in rotating and alternating magnetic fields depend on the strength of the magnetic field. For water-in-oil (W / O) droplets, they can be stabilized in a magnetic field and form a crowded fluidized bed, thereby significantly increasing the rate of extraction, especially during countercurrent operation, which increases the effective contact between the phases This suggests a mix of moving bed and spray column with magnetic W / O droplets.
