Because the real bio-membranes and the tranporting processes realized across them are very complicated, the model membranes have been used for elucidation of the basic transporting steps. In the contribution, the different possibilities of characterization, description, and elucidation of the transport processes on the example of some metal ions and theor complexes, i.e., of cadmium, lead, and copper, were presented. It summarizes the results achieved using supported phospholipid model membranes formed on porous membranes and on agar support. Discussed transporting processes of selected ions have been characterized using two electrochemical methods: electrochemical impendance spectrometry (EIS) and voltammetry. The impact of some parameters on these systems and processes was investigated.
