抄録

A study was made of the transport through a 1, 2-dichloroethane liquid membrane of two kinds of zwitter ionic compounds, dodecyldimethylammoniododecaneimidate (AI) and (1-tetradecyl-2-pyridinio) -octanesulfonimidate (PY), as carrier molecules. <BR>Halide ions were sym-ported with hydrogen ions, almost completely so by AI. The rate of transport of AI or trioctylamine (AM) was much faster than that of PY or perhydrodibenzo-18-crown-6. For iodide ions, the rate by AI was faster than that by AM. <BR>Phenylalanine was counter-ported by AI, as well as AM, in the opposite direction to hydrogen and halide ions, against its concentration gradient. The flux was 2×10-3mol·cm-2·mol-1·h-1. This result along with the fact of permanganate ion extraction, indicate ion release to be the rate determining step for the transport of phenylalanine by AI.
