Development of a microfluidic-chip system based on parallel flow for intensified Gd(III) extraction from nitrate media using cationic extractant

Critical elements: opportunities for microfluidic processing and potential for ESG-powered mining investments

“…To achieve a more efficient method for extracting Gd, the Y-Y microchannel used by Abbasi et al was capable of separating Gd with a yield of up to 95.5% in optimal conditions. 91 As shown in Fig. 11, under a low concentration of Gd (2.9 vol%), their system managed to perform the extraction in 13.5 s. This highlights the potential of microfluidics for extracting strategic metals at low concentrations in a simple, fast and effective process.…”

Transition of chemical engineering from macro to micro/nano scales

“…Solvent extraction microfluidic equipment has been developed for a wide range of applications, including metal ion separation and DNA purification [39][40][41][42][43][44][45][46][47]. Sarkar, et al investigated liquid-liquid biphasic flow patterns in microchannels [48].…”

Microreaction and membrane technologies for continuous single-enantiomer production: A review

“…Enantiomerically selective membranes separate mixtures of optical isomers, such as pharmaceutical enantiomers, amines, or amino acids and their derivatives. [109,110] These membranes can be divided into two basics groups: i) liquid membranes [104,[111][112][113][114] and ii) solid membranes. [115][116][117] The separation principle is based on specific interactions of atoms and/or groups of atoms of an enantiomer molecule with the surface atoms or groups of atoms at the membrane surface.…”
