چکیده
|
This paper reports the selective determination of carbidopa (cd) in the presence ofuric acid (ua) using 2,7-bis(ferrocenyl ethyl)fluoren-9-one modified carbon nanotube pasteelectrode (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 to22.0 ?m and, the other is 22.0 to 750.0 ?m. the detection limit (3?) obtained by dpv was68.0 nm. the practical application of the modified electrode was demonstrated bydetermining cd in urine samples .
