Abstract
This paper reports the selective determination of carbidopa (CD) in the presence of
uric acid (UA) using 2,7-bis(ferrocenyl ethyl)fluoren-9-one modified carbon nanotube paste
electrode (2,7-BFCNPE) in 0.1 M phosphate buffer solution (PBS) pH 7.0. In PBS of pH 7.0,
the oxidation current increased linearly with two concentration intervals of CD, one is 0.2 to
22.0 ?M and, the other is 22.0 to 750.0 ?M. The detection limit (3?) obtained by DPV was
68.0 nM. The practical application of the modified electrode was demonstrated by
determining CD in urine samples .
