Abstract
A new microfluidic extraction method using a gas-liquid-liquid double emulsion with ultra-thin solvent film as the working system was developed, overcoming the defect of low extraction efficiency at extreme phase ratios (R > 10) by significantly reducing the mass transfer distance. Interesting bubble coalescence in the emulsion generation was reported and laws of bubble diameter (0.73-1.08 mm) and film thickness (0.35-4.06 μm) were proposed. Simulated by a Sudan IV extraction process, the gas-liquid-liquid extraction showed 16-28.3 times working efficiency compared to liquid-liquid extraction, appropriate for application requiring fast analysis and detection.
