Abstract

The work described in this thesis encompassed a study concerning the redox behaviour of three groups of compounds, namely an Carylazo- 5-methyl-2-phenyl-3-pyrazolone and some of its derivatives, an arylazopentane2, Cdione and some of its derivatives, and thirdly some iron containing compounds (some derivatives of ferrocene crown ethers and Bis (n-qclopentadienyl iron). In addition voltammetric methods have been used in this thesis to provide additiorlal information. The electrochemical techniques used in the present study are: (i) D.C.Polarography, (ii) Cyclic Voltammetry, (iii) chronoamperometry, (iv) chronocoulometry, (v) chronopotentiometry, and (vi) Controlled Potential Electrolysis. The electrochemical data have been treated by convolution and deconvolu tion trans formations. Digital simulations using the kinetic parameters etc were also performed. Finallv the mechanism of the electrode reaction was deduced for the three groups of compounds under investigation. In what follow, a brief description of the different chapters reported in this thesis is given: I) In the first chapter, the principles of electrochemistry includes a wide range of experimental techniques, convolution transform of electrochemical current functions and its application to CV, CA and CP, deconvolution of the Nernstian current function, evaluation of the firstorder chemical rate constant kc through the use of the I, transform of an EC,,, electrode process and finally the use of digital simulation in elect roc hem is^ have been discussed.
