Electrochemical Determination of Dopamine on a Glassy Carbon Electrode Modified by Using Nanostructure Ruthenium Oxide Hexacyanoferrate/Ruthenium Hexacyanoferrate Thin Film
Figure 4
(A) Cyclic voltammograms obtained on the bare GC (a1) and GC/RuOHCF/RuHCF modified (a2) electrodes in the presence of 0.2 mM DA at pH 5. Scan rate 100 mV/s. (B) Complex plane plots obtained in 0.1 M NH4NO3 in the presence of 1 mM DA at pH 5 on (a) the bare GC, and (b) GC/RuOHCF/RuHCF modified electrodes. V versus Ag/AgCl, mV, and frequency range: 10 kHz to 10 mHz.
