Author Description

Manganese is an essential metal which is involved in several natural procedures that electron transfer reactions occur. Thus, over the past decades electrochemists have spent a great deal of efforts in solving the problem of manganese oxidation and reduction mechanism. Meanwhile, manganese could be toxic and therefore sensitive, low cost, rapid and selective detection methods should be developed. This book complements the existing information about the voltammetric behaviour of manganese(II) ions. Furthermore, a mechanistic scheme of its oxidation and reduction is proposed, which could be useful in understanding its electrochemical properties. Besides, adsorptive stripping voltammetry as fast and sensitive technique was employed in the analytical determination of manganese(II) ions at a carbon paste electrode. The results have been proven to be promising for the future manganese detection in real samples. Furthermore, based on the nucleation and growth properties of the resulted MnO2 on carbon paste electrode, it could be used as a coating material on a chip device or as a chemical modifier of electrode surfaces to provide better detection limits.
