Abstract Amino acid hydrochlorides are well transported through 1-decanol membranes containing Kryptofix 5 or 222 and supported in a porous polyacrylonitrile hollow fiber matrix. Factors which influence the transport of phenylalanine hydrochloride were studied in some detail using this sheet- as well as hollow fibre-supported liquid membranes. These studies show that the choice of the membrane phase, the kind of polymeric support and the mode of membrane preparation are of great importance for the efficiency of the process. The most vital step in the membrane preparation appears to be its activation by soaking in a solution of phenylalanine hydrochloride in a water-ethanol or water-propanol mixture. This probably improves the contact between membrane and the aqueous phase.
