Liquid-liquid extraction in a novel rotor-stator spinning disc extractor

This work describes a novel rotor-stator spinning disc extractor (RSSDE), which shows high efficiency of liquid-liquid mass transfer and rapid separation of mixed phases in comparison to conventional extractors. Extraction of phosphoric acid from an aqueous phase to an organic phase was selected as the experiment system. The influence of rotational disc speed (R), volumetric flow rate (Q), and rotor-stator distance (H) on extraction efficiency...
