Determination of Chromium in Natural Water by Adsorptive Stripping Voltammetry Using In Situ Bismuth Film Electrode
Figure 2
The stripping voltammetry DP-AdSV using in situ BiFE of chromium is recorded for (a) Edep = −800 mV and (b) tdep = 50 s. (c) NaNO3 concentrations are changed: the bottom line is the baseline, followed by concentration of NaNO3 increasing from 0.1 to 0.4 M. Other experimental conditions are as shown in Figure 1.
