Sažetak

We present a general thermodynamic method to obtain information about co-adsorption and oo-partitioniiug of low molecular weight ions upon adsorption or partitioning of proteins between two phases. Esin-Markov coefficients are central quantities. By this procedure useful additional information is obtained that, in turn, can be used in mechanistic interpretations. Applications are presented for (1) ion binding to free BSA, (2) charge adjustments in the protein and on the surface upon adsorption of BSA on silver iodide and (3) ion co-participation upon solubilization of cytoohrome-C into micro-emulsdon .droplets.
