Electrochemical determination of the superoxide ion concentration from KO2 dissolved in dimethyl sulfoxide.
An electrochemical determination of the O2- concentration from KO2 in DMSO solution using steady state microelectrode voltammetry shows that the KO2/DMSO method with the combined use of a crown compound or sonication is a reliable and simple technique for introduction of O2- to the biomimitic reaction system.
