Electrochemiluminescence Analysis of Levodopa using Luminol at MWCNT-Modified Electrode
نویسندگان
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.
