dc.description.abstract |
Edged plane pyrolytic graphite electrode (EPPGE) was modified with and without Prussian blue (PB)
nanoparticles and polyaminobenzene sulphonated single-walled carbon nanotubes (SWCNTPABS) using
the chemical deposition method. The electrodes were characterised using microscopy, spectroscopy and
electrochemical techniques. Results showed that edged plane pyrolytic graphite-single-walled carbon
nanotubes-prussian blue (EPPGE-SWCNT-PB) electrode gave the best dopamine (DA) current response,
which increases with increasing PB layers. The catalytic rate constant of 1.69
×
105 mol−1 cm3 s−1, Tafel
value of 112 mV dec−1, and limit of detection of DA (2.8 nM) were obtained. Dopamine could be simultaneously
detected with ascorbic acid. The electrode was found to be electrochemically stable, reusable
and can be used for the analysis of DA in real drug samples. |
