Voltammetric Determination of Uric Acid in Clinical Serum Samples Using DMF Modified Screen Printed Carbon Electrodes

Figure 5

Differential pulse voltammetry of UA (1 mM), AA (100 μM), and 100 μM CA in a 0.1 M PBS (pH 7.0) and (II): different concentrations of UA (100 μM (a), 500 μM (b), and 1 mM (c)) in the presence of 100 μM each of AA and CA in a 0.1 M PBS (pH 7.0) at the DMF modified SPCE at scan rate of 10 mV/s, pulse amplitude of 240 mV, and pulse period of 100 ms.
