Abstract

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.
