“…However, due to the chemical resemblance of lanthanides, it is difficult to achieve their separation thus cascade separation operation with thousands of mixer-settler has to be implemented [1]. Integration of microfluidics into solvent extraction can introduce many benefits for improving interface mass transport, such as shortening the mass transport path and enlarging surface-to-volume ratio [4,5].…”

Droplet-based microfluidic extraction is a promising way for effective lanthanides extraction due to its outstanding mass transfer performance. The separation process can be greatly enhanced with the droplet-based microfluidic extraction technique. However, the interactions between mass transfer, microfluidic dynamics and extraction kinetics are still unclear, which has hindered further manipulation on microfluidic extraction to boost extraction performance. In this study, the mechanisms of microfluidic droplet-based extraction and separation intensification of lanthanides are for the first time unveiled by using a numerical simulation model. The limiting factors for the performance of droplet-based microfluidic extraction are identified through a model-based parametric analysis. The numerical analyses provide a comprehensive understanding of droplet-based microfluidic extraction systems and offer operation and optimization guidelines for future research in this area.

In this study, firstly, a double‐reservoir and switchable prototype of a micro‐chip along with the respective holders were fabricated. A cyclic desorption process using microliter volume of organic solvent was adopted to prevent any outdoor contamination. As extractive phases, two identical sheets of electrospun polyamide/polypyrrole/titania nanofibers were synthesized using core–shell electro‐spinning technique and utilized for determination of memantine in plasma samples. Field emission scanning electron microscopy images showed a high degree of porosity and homogeneity throughout the sheet structure. Also, energy dispersive X‐ray analysis confirmed the presence of titania, while the recorded Fourier transform infrared spectra proved the chemical structures of the polymeric mats. The incorporation of titania as well as polypyrrole in the composition of polyamide nanofibers improved both mechanical stability and extraction capacity of the extractive phase and therefore facilitated the extraction/desorption process. The limits of detection and quantification were 0.01 and 0.04 ng/mL, respectively. In addition, the interday and intraday precisions were lower than 6.7% (n = 3). The linearity was in the range of 0.14–75.00 ng/mL, while recoveries were between 94.1 and 98.4% with the regression coefficient of 0.9987.

“…Because microstructured devices are inherently characterized by a high surface‐to‐volume ratio, they are predestined for advanced extraction strategies that enable increased mass transfer, while reducing the overall amount of solvent required . However, one of the most challenging tasks for the transfer of solvent extraction to microdimensions is stabilization of the liquid‐liquid interface.…”

Although microfluidic solvent extraction (mSX) is a recent field in separation, its application is still limited to single-channel microfluidic devices. However, the industrial application of microheat exchangers has already proven that parallelization of microchannels is an important tool to increase the specific device efficiency. Hence, in this study, a multichannel system for mSX is introduced. As a model process, D,L-5-phenylhydantoin was extracted from ethyl acetate into aqueous buffer. By means of different experimental setups, the potential and limitations of membrane-supported multichannel mSX were investigated. The reactor dimensions perpendicular to flow and transmembrane mass transport are the most challenging factors for the introduced device.
