MICROFLUIDIC DROPLET-BASED LIQUID-LIQUID EXTRACTION FOR FLUORESCENCE-INDICATED MASS TRANSFER

This paper demonstrated a fluorescence-indicated mass transfer liquid-liquid extraction process based on a droplet microfluidic system. Analysis of the droplet-based liquid-liquid extraction process based on the description of mass transfer into or out of droplets is conducted. The relationship between the extraction efficiency and the droplet size is measured and the mass transfer coefficient for fluorescein from octanol to PBS buffer is determined as 3.07 × 10 -5 m/s.
