چکیده
|
Levedopa was sensitively determined based on electrogenerated chemiluminescence (ecl) mechanism through enhancing the weak ecl of electro-oxidized luminal in presence of levodopa, on a multiwall carbon nanotubes (mwcnts)-modified electrode. under optimal conditions, the relative ecl emission/levodopa concentration plot was found to be linear from 1.0×10^-9 to 1.7×10^-7 m and a detection limit of 6.7×10^-10 m was recorded. the modified electrode was found applicable to the analysis of levodopa in urine samples.
