Özet:

 

In this paper, the possibility of using an   electrochemically activated carbon-paste electrode (ECA-CPE) for the   determination of morin has been studied. It is established that the   oxidation current increases 1.85 times in comparison with untreated CPE. The   adsorption nature of the anodic current and the number of electrons taking   part in the oxidation of morin on ECA-CPE was established. The optimal   conditions for the determination of morin (pH === 4, Eads=ads=_{ads\, }= 200~mV,   tads=ads=_{ads\, }= 180 s) were established. Using square-wave voltammetry (A   === 35 mV, ν=ν=\nu  = 25 Hz, υ=υ=\upsilon  = 100 mV/s) it is possible to   determine morin in the range of concentrations of 6-0.8 μM (with   0.314 μA\μM sensitivity) and 0.8-0.16 μM (with 0.557   μA/μM sensitivity). The developed sensor was tested for the   determination of morin in model solutions and Coffea arabica extracts with RSD lower than   4.5%.
