(a) Linear regression line for the SqW-AdSV method; (b) stripping voltammetry of SqW-AdSV method: the bottom line is the baseline, followed by nine additional standard lines, each adding 0.2 ppb; (c) relation between Ip and CCr(VI) when examining the linear range of the DP-AdSV method; (d) linear regression line for the DP-AdSV method. Experimental conditions are as shown in Table S2.
