Permeation of 6-nitro-3-phenylacetamide benzoic acid (NIPAB) and hydrolysis by penicillin acylase immobilized in emulsion liquid membranes.
TL;DR: Both the rate of permeation and potassium transfer significantly increase when hydrophilic surfactants are present and there was no relationship observed between potassium cation transfer from the internal phase and emulsion stability in the storage test.
