Abstract

Flow velocity profiles of micro counter-current flow of aqueous and butylacetate phases in a microchannel having a width of 100 μm were measured by micro particle image velocimetry. In order to analyze the hydrodynamic characteristics of the counter-current flow, we derived a simple analytical model for the velocity profile. When flow rates of the aqueous and organic phases were 0.2 and 0.1 μl/min, the model agreed well with the experimental results. Predictions about the velocity profile will contribute to estimation of the extraction efficiency in the co-current and counter-current extraction process. 2007
