EFFECT OF THE NUMBER OF SUBSTITUENTS ON THE BEHAVIOR OF MODIFIED ELECTRODES WITH COBALT PORPHYRINS SUBSTITUTED WITH A DIFFERENT NUMBERS OF BIS(METHOXYPHENYL) GROUPS TOWARD THE OXIDATION OF SULFITE

EFFECT OF THE NUMBER OF SUBSTITUENTS ON THE BEHAVIOR OF MODIFIED ELECTRODES WITH COBALT PORPHYRINS SUBSTITUTED WITH A DIFFERENT NUMBERS OF BIS(METHOXYPHENYL) GROUPS TOWARD THE OXIDATION OF SULFITE

In this study, we compared four glassy carbon electrodes modified with adsorbed porphyrins of cobalt containing one, two, three, or four bis(methoxyphenyl) groups as substituents of the ligand. The aim of this work was to determine the effect of these donating groups on the electrocatalyst behavior...
