font size="1" face="GulliverRM"> This work proposes the amperometric determination of hydrogen peroxide reduction and oxidation as a tool for the characterization of La1−xAxMnO3 perovskites dispersed in a graphite composite electrode (carbon paste electrode, CPE). The catalytic activity of perovskites towards the oxidation an
