| Abstract: | Electrochemical behaviour of 2-[4'-(substituted)
sulphonamoyl- phenyl]hydrazono ethyl-2-cyanoethanoate (SHEC) in
Britton-Robinson buffers (pH 2.05-10.5) showed that all
SHECs gave a single reduction wave at dropping mercury electrode.
Cyclic voltammograms exhibited a well defined
irreversible cathodic peak at glassy carbon electrode. On the basis of DC,
differential pulse polarography and cyclic voltammetry,
a reaction mechanism has been suggested. Kinetic parameters [charge
transfer coefficient ( na), forward rate constant (k°f,h) and
diffusion-coefficient] have been calculated by polarographic and cyclic
voltammetric methods. A plausible mechanism has also
been suggested on the basis of protons involved in rate determining step
and number of electrons
involved in reduction process. |
