Figure 8
(a) CV curves of bare carbon cloth at various UA concentrations in phosphate-buffered solution (10-200 μM). Inset shows the calibration plot for UA concentration. (b) Cyclic voltammograms of h-BCN-modified electrode at various DA concentrations (10-580 μM) in phosphate-buffered solution (pH 6.8). Inset shows the calibration plot for UA concentration. Scan rate, 10 mVs−1. (c) The calibration plot for UA concentration from 10 to 300 μM. (d) Amperometric response of h-BCN-modified electrode at 0.65 V for the successive microadditions of DA to buffer solution (corresponding to 10–200 μM). Inset shows the calibration plot for DA concentration.
