Our work studied the effect of selected organometallic chloride compounds on electrical properties of membrane, in the form of hydrophilic filters impregnated with lauric acid. The presence of the compounds in the membrane surroundings induced a quick increase of the membrane voltage that decreased more slowly after reaching the maximum value, and stabilized after a lapse of a specified period of time. In the case of triphenyltin, the voltage changed direction during measurement and stabilized in negative values. Based on the results obtained, it was found that the effectiveness of the interaction of the compounds studied with the membrane is highest in the case of triphenyltin chloride. The change of voltage polarization in the case of triphenyltin may denote that chlorine ions released in the dissociation process penetrated the other side the membrane.
