Abstract: Astudy of the monovalent cation transport through BLMmodified by five kinds of bis-crown ethers using electrochemical measurements is presented.An investigation of the BLMpotential, ion selectivities and current on the membrane has been carried out and the experimental results indicated that using BLMwe can compare the selcctivities for some monovalent cations of various bis-crown ethers which have similar molecular structure and chemical properties.

Key words: Membrane, Selectivity, Bis-crown ether
