Аннотация: The adsorption of methylpyridinium (MP//y** plus ) as the aromatic cation was studied in combination with SO//4**2** minus , Cl** minus , Br** minus , and I** minus as the anions, following an approach similar to that used when studying cations left bracket (C//2H//5)//4N right bracket ** plus . It is shown that adsorption isotherms of MPyI found via the Gibbs relation for two values of potential are reported. One can see that in this case the GAMMA -values increase monotonically with concentration, and substantially exceed the GAMMA //m-value obtained for (MPy)//2SO//4. In addition, in the case of MPy** plus ions the halide ions, owing to the possible formation of charge-transfer complexes, have an even stronger effect on the adsorption behavior of the organic cations than had been observed previously in the case of tetraalkylammonium ions.
