In this work, a novel rotating microchannel extractor (RME) is designed and further used for the extraction of chromium (III) from water. Unexpectedly, the micro-extraction had the same effect as carrying out 2.9-stage cross-flow extractions. Various factors, including the gas intake methods, gas intake quantity (Qg), distance between inner rotor and outer wall (D), rotational inner rotor speed (R) and volumetric flow rate (Qa, Qo), were selected to investigate their effect on the extraction efficiency (η) thoroughly. The relation map of η with Wea and Weo−g for RME provides a comprehension for the gas–liquid–liquid extraction process in this RME system.
