چکیده
|
A cationic surfactant tetradecyl trimethyl ammonium bromide modified carbonpasteelectrode (ttabmcpe) was fabricated and the electrochemical behavior ofnorepinephrine at the modified electrode was investigated by cyclic voltammetric anddifferential pulse voltammetric techniques. a well-defined oxidation peak was observed at174 mv and the significant increase in peak current at modified carbon paste electrodecompared to bare carbon paste electrode was obtained. the effect of scan rate on theoxidation of norepinephrine was examined and it was found that the anodic peak current wasproportional to the concentration of norepinephrine in the range from 0.10 ?m to 4 ?m.comparedwith other reported electrochemical method; this new sensingmethod has highersensitivity, rapid response and extreme simplicity. ttabmcpe was used for thesimultaneous determination of nor norepinephrine, ascorbic acid and uric acid.the analyticalperformance of this biosensor has been evaluated for the detection of norepinephrine ininjection sample
