Cyclic Voltammetry Analysis of Au-Cr Coated Electrode with Albumin Interference at pH 3.51

This study presents data on peak currents obtained from cyclic voltammetry using an Au-Cr coated electrode on a silicon wafer. The electrode was tested in an electrolyte solution of 0.5 M KCl containing 20 mM K₄Fe(CN)₆ and 20 mM K₃Fe(CN)₆, with a scan range of -0.20 to 0.60 V and a scan rate of 0.05 V/sec. The influence of 8 ppm albumin as an interference on the peak currents at a pH of 3.51 (using 1N HCl) was assessed at an adsorption temperature of 37-38°C, as detailed in Table VII.
