Abstract

The redox behaviour of manganese system in Mn-Sac and Mn-Sac-Phen complexes were studied using cyclic voltammetry technique at glassy carbon electrode (GCE) in 0.1 M KCl electrolyte. The CV of Mn-Sac solution is more or less similar to that of uncoordinated Mn (in MnCl₂) accept slight difference in peak position and peak current. The presence of secondary ligand phenanthroline (in Mn-Sac-Phen complex) changes the CV of Mn system largely compared to those of uncoordinated Mn and Mn-Sac. The redox system is irreversible in Mn-Sac and quasi-reversible in Mn-Sac-Phen complex. The effect of concentration and pH on the redox behaviour of Mn system have been studied for both the complexes.
