ABSTRACT:
The described apparatus is a multilayer liquid membrane support structure that can be used in devices for separating or purifying a desired chemical species. A inner layer is sandwiched between two outer layers to provide a porous support for a liquid membrane subject to oscillatory motion at a frequency selected to promote enhanced mass transport of the chemical species across the liquid membrane. The pores of the inner layer are selected to have an average pore diameter less than the pores of the outer layers.
