Investigations on the redox behaviour of manganese in manganese(II)‎-saccharin and manganese(II)‎-saccharin-1,10-phenanthroline complexes

الملخص EN

The redox behavior 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 KC1 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 behavior of Mn system has been studied for both the complexes.
