The cellular automaton method was used to simulate the process of ion desorption from the surface of lipid membranes modified with a mixture of cationic and anionic amphiphile molecules. Three models were devised to analyze the influence of anionic long-chain and cationic long-chain compounds, and a mixture of anionic short chain and cationic long chain compounds on bipositive ion desorption. The obtained results are compared with experimental results. These models show the significance of some hypotheses on the role of temporal complexes of the alkylsulphonate anion and calcium ion, of readsorption of calcium ions, and of different methods of molecular aggregation on the kinetics of calcium desorption.
