Ferrocene Carboxylic Acid Reaction Paper

1. Introduction

1.1 Objective of the Research:

The Objective of this research is twofold, first to quantify the information content of the cyclic voltammogram data and understand the kinetic parameters that are involved in redox reaction and simulate them using acquired information, also identify the post oxidation peak that occurs at slow scan rates in the presence of air. Second, to check the electrochemical reduction of nitrate ion at the surface of different working electrodes that are available in the lab at neutral and alkaline systems.

1.2 Importance of the Research:

Ferrocene carboxylic acid, as an iron centered inorganic derivative of ferrocene, behaves as a simple and ideal reversible redox system and is commonly used as mediator with enzymes such as glucose oxidase. , ,

However, during extensive use of Ferrocene Carboxylic Acid, FCA, in this research study,

Cyclic voltammetry is used in this study, thus more detailed discussion is given below.

2.2 Theory and Principles of Cyclic Voltammetry

The expression cyclic voltammetry simply specifies the relationship between the potential of an electrode and species (designated O and R) involved in the Redox (reduction/oxidation) reaction at that electrode.

2.2.1 Theory: The Nernst Equation, Mass Transfer and Fick’s Law:

Oxidation or reduction of a species depends on the potential applied on the working electrode. Let us consider following reaction that can be adopted for FCA couple; aO + ne-  bR (1)
Where, O is reactant species which is being reduced to product R, and a and b are their respective reaction coefficients, the reaction quotient Q is defined as; Q = [R]b/ [O]a (2) Fe3+ +1e-  Fe2+ (3)
The reaction quotient in terms of FCA redox couple; Q = [Fe2+] b/ [Fe3+] a
