Camplex fonnation constants with sodium and potassium ions follow the selectivity order determined by EMF. measurements on liquid membranes: nigericin: K\(^+\) >Rb\(^+\)> Na\(^+\)> Cs\(^+\) >Li\(^+\); monensin: Na\(^+\)> K\(^+\) >Li\(^+\)> Rb\(^+\)> Cs\(^+\). Transport experiments show that nigericin and monensin facilitate the diffusion of potassium ions across model membranes, although in electrolytic transport experiments the permeability is not affected.}, subject = {Toxikologie}, language = {de} }
