Solvent extraction (SX) is an important separation method with countless applications in the chemical industry. The water/oil interface is an essential feature of SX systems. Microfluidic technology is ideally suited for exploitation in SX due to intrinsic advantages of the micro dimensions that result in laminar flow conditions, high surface-to-volume ratio and the reduced chemical quantities needed. This review describes the use of microfluidic devices in SX.

“…Raman spectroscopy and UV–vis absorbance , are the most relevant analytical techniques to measure actinides concentrations in aqueous solutions. Several implementations for in-line monitoring of separation processes at the lab-scale have been recently reported. − In each case, the fluid is pumped to commercial small-volume flow-cells where the analysis is performed. However, these Z-shape type flow-cells do not allow to tune independently the sample volume and the optical path-length, which becomes especially convenient as we demonstrate hereafter.…”

Uranium(VI) On-Chip Microliter Concentration Measurements in a Highly Extended UV–Visible Absorbance Linearity Range

The reduction of effluents deriving from analytical control is a serious concern in the nuclear industry, for both production and R&D units. In this work we report an alternative methodology for the standard UV-vis absorbance analyses for actinides concentration monitoring along the plutonium uranium refining extraction (PUREX) process. This methodology, based on photonic lab-on-a-chip (PhLoC) technology, enables drastic sampling reduction down to a few microliters and simultaneously allows to track concentrations over several orders of magnitude while maintaining a detection linearity range. A PhLoC microfluidic platform was specifically designed to allow online sample injection with zero dead volume connectivity and the on-chip spectrophotometric approach, based on a multiple optical path configuration, was tested for the determination of uranium(VI) concentrations from 0.1 to 200 g L, showing that linearity is maintained within high levels of confidence. These results provide the proof of concept for the transposition of current analytical methods for actinides, including plutonium, to microfluidic systems.
