Determination of Chromium in Natural Water by Adsorptive Stripping Voltammetry Using In Situ Bismuth Film Electrode
Figure 3
The stripping voltammetry lines were repeated: (a) according to the SqW-AdSV method (n = 7) with CCr(VI) = 1 ppb; (b) according to the DP-AdSV method (n = 9) with CCr(VI) = 2 ppb. Other experimental conditions are as shown in Table S2.
