M. Ersoz et al., TRANSPORT STUDIES OF AMINO-ACIDS THROUGH A LIQUID MEMBRANE SYSTEM CONTAINING CARBOXYLATED POLY(STYRENE) CARRIER, Journal of membrane science, 104(3), 1995, pp. 263-269
Transport mechanisms have been studied for amino acids such as p-amino
benzoic acid and phenylalanine moving through a bulk organic liquid m
embrane system containing carboxylated poly( styrene) carrier. The tra
nsport in this system, in which one side of the membrane was acidic an
d the other side was alkaline, was influenced significantly by the ini
tial H+ ion concentration on the acidic side. The passage of amino aci
ds through the organic bulk liquid membrane was governed by an electro
chemical interaction between carboxyl groups in the membrane and trans
porting materials.
