Digital simulation of the cyclic voltammogram for the ion transfer through a liquid membrane of thickness from 1 mm to 10 nm was performed. The magnitude of current and the shape of the voltammogram simulated for extremely thin membrane (10 nm thick) were similar to those observed experimentally with a bilayer lipid membrane, BLM, of about 10 nm in thick, when the diffusion coefficient of an ion in the BLM was assumed to be extraordinary small (10 −13 to 10 −14 cm 2 s −1 ).
