Studies on Crown Ether Coordination Compounds (ⅩⅣ)——The Transport of Potassium Ions by 2,3-Benzo-11-Methyl-18-Crown-6 Liquid-Membrane-Mimicking Cell Membranes

Abstract

Abstract: Liquid membranes containing 2,3-benzo-ll-methyl-18-crown-6(BCl-18C6) is able to transport metal ions against their concentration gradient.The migration of metal ions is a consecutive first order process when the concentrations of metal ions in source phase and of carriers in membrane phase are comparable, the transport rate is proportional to the difference between the product of cation and anion concentrations in source phase and that in receiving phase.The influence of stirring rate on the transport mechanism was considered.

Key words: Crown ether, Potassium ions, Liquid membrane, Transport rate, Mimicking
