Abstract
A modified platinum electrode was fabricated by the electropolymerization of
pyrrole using a sodium p-sulphonatocalix[6]arene as the supporting electrolyte. The
modified electrode acts as a reasonably sensitive electrochemical sensor for dopamine
giving a linear calibration curve in the range 0.075 – 1.00 mM dopamine. The sensor
shows no ability to sense the common interferent ascorbic acid, therefore the concentration
for dopamine can be directly sensed in a large excess of ascorbic acid with no need
to make adjustments for the signal for ascorbic acid. Investigations are included to study
the mode of sensing of the modified electrode.
