Surfactant-stabilized　multiphase　emulsions　are　widely　used.　However,　current　studies　on　the　dynamic　adsorption　of　emulsions　during　flow　are　mainly　focused　on　the　droplet　formation　stage　rather　than　the　flow　stage.　In　this　study,　the　mass　transfer　of　surfactants　in　microchannels　during　the　droplet　formation　and　flow　phases　(the　overall　process)　was　investigated　and　a　mass　transfer　diffusion　model　and　an　adsorption　kinetic　model　for　emulsions　were　developed,　which　explained　the　mass　transfer　process　in　microchannels　for　low　and　high　surfactant　concentrations,　respectively.　Subsequently,　dynamic　interfacial　tension　values　between　the　two　phases　were　calculated　using　two　surfactants　(SDS　and　DTAB)　to　validate　these　models　and　the　results　were　in　good　agreement　with　the　experimental　values.　This　study　contributes　to　a　deeper　understanding　of　how　surfactants　diffuse　throughout　three-phase　emulsions,　thus　shedding　light　on　the　mass　transfer　mechanisms　inherent　in　these　complex　systems.
