Figure 2From: Silver-functionalized carbon nanofiber composite electrodes for ibuprofen detectionRecorded cyclic voltammograms. These were recorded at (a) AgCNF, (b) AgZCNF electrodes in 0.1 M Na2SO4 supporting electrolyte (curve 1) and in the presence of various IBP concentrations that consists 1 to 8 mg.L−1 (curves 2 to 9); potential scan rate of 50 mV s−1. Inset: calibration plots of peak current vs. IBP concentration.Back to article page
