Abstract
In this paper a method is presented for determining the permeability coefficient of bilayer lipid membrane (BLM) for porphyrins by UV/Vis spectrophotometry. BLM is formed on the hole separating two compartments of the cell. The coefficient permeability of BLM is calculated for meso-tetra-[4-N-(2'-hydroxyethyl)pyridyl] porphyrin. The proposed method can be used to determine the permeability coefficient of BLM for other substances.
