Electrochemical Determination of Dopamine on a Glassy Carbon Electrode Modified by Using Nanostructure Ruthenium Oxide Hexacyanoferrate/Ruthenium Hexacyanoferrate Thin Film

Table 3

Results of the recovery tests obtained for determination of DA in real sample (DOPADIC ampoule) after dilution to different concentrations. Results are average of four measurements on each sample.

𝐶DA/μM (Expected)	𝐶DA/μM (Recovered)	Recovery %	% RSD (Recovered)
4.98	5.03	101.03	1.50
7.47	7.37	98.70	1.30
9.95	10.00	100.50	2.36
66.60	67.50	101.35	3.89
