Mass transfer studies in a micromixer-settler: extraction of Cs and Sr with CCD-PEG-400 solvent from simulated acidic radwaste solutions

Solvent extraction of Cs(I) and Sr(II) from a simulated radwaste acidic solution was studied with chlorinated cobalt dicarbollide/polyethylene glycol-400/FS-13 solvent in a microfluidic channel based miniature extractor with qualitative extraction. Extraction and stripping kinetics for Cs(I) and Sr(...

Beschreibung
Zusammenfassung:	Solvent extraction of Cs(I) and Sr(II) from a simulated radwaste acidic solution was studied with chlorinated cobalt dicarbollide/polyethylene glycol-400/FS-13 solvent in a microfluidic channel based miniature extractor with qualitative extraction. Extraction and stripping kinetics for Cs(I) and Sr(II) was found to be much faster than that observed in batch equilibration studies.
