Predict and compare the formation of segmented flow in microsystems: Interest for radiochemical liquid-liquid extraction

Abstract : One of the most important separation techniques in radiochemical procedures is solvent extraction. In the last decade, a growing interest in its use in microsystems has emerged because such systems allow a good control of both the interface area between aqueous and organic phases, and the contact time of the two phases. To improve mass transfer in liquid-liquid extraction reactions for radiochemical separation relevant to the nuclear field, our goal is to implement liquid-liquid extraction with segmented flows in microsystems in order to increase the interfacial area. The optimization of the interfacial area requires taking into account the hydrodynamics of biphasic systems. This study is dedicated to the understanding of segmented flows in a T-junction with the aim to form tailor-made droplets for given organic and aqueous phases.
