Abstract: The effect of selected surfactants and inorganic salts on the time stability of perchlorate of diethazine cation radical was studied in an aqueous acid solution (3 M-H₃PO₄). The stability of cation radical was increased only by ClO₄^- in the presence of low concentration of anionic surfactant and nonionic surfactant over the whole studied surfactant concentration region, but the values of time stability are always lower than those observed in the presence of only ClO₄^- without surfactant. In all inorganic salt-surfactant mixtures the stability of diethazine radical cation corresponds, to the first approximation, to superposition of the effects of individual components, where the effect of one of them can predominate at high concentration.
