Voltammetric resolution of dopamine in the presence of ascorbic acid and uric acid at poly (calmagite) film coated carbon paste electrode

Electrochemical behavior of poly (naphthol green B)-film modified carbon paste electrode and its application for the determination of dopamine and uric acid

“…The LOD was calculated using the following equation, LOD = 3 S/M where, S is the standard deviation and M is the slope (sensitivity) obtained from the calibration curves [45].…”

Voltammetric Resolution of Dopamine in Presence of Ascorbic Acid and Uric Acid at Poly (Brilliant Blue) Modified Carbon Paste Electrode

“…The -SO 3 H group of poly (brilliant blue) could dissociate favorably into a negatively charged SO 3 -group under this condition the -NH 2 group of DA could obtain a proton and form the positive ion of DA. Therefore the negative charge -SO 3 -on the surface of poly (brilliant blue) MCPE has a well affinity to the DA positive ions and could catalyse and promote the oxidation of DA [32][33][34].…”

Cyclosporine/SDS Modified Carbon Paste Electrode for Electrochemical Study of Dopamine: A Cyclic Voltammetric Study

“…The scan rate varying study showed that current improved linearly with the square root of scan rate range of 50 to 400 mVs -1 The graph of anodic peak current (Ipa) versus the square root of scan rate showed a linear relationship of Ipa and scan rate. The correlation coefficient was found to be 0.9950 Figure 3b it indicates that the electrode process was diffusion controlled [32][33][34][35]. The difference between the anodic and cathodic peak potential (Δ Ep) increasing with increasing the scan rate [36][37][38].…”
