In addition to the influencing factors, the stripping voltammetry performance factors such as deposition potential, deposition time, equilibration time, cleaning potential, cleaning time, and technical parameters of differential pulse and square wave voltammetries have been investigated, and the influence of Cr(III), Co(II), Ni(II), Ca(II), Fe(III), 所以 4. 2 - ,Cl.-而且也调查了Triton X.该方法具有良好的重复性,具有RSD <4%( N. = 9) for the differential pulse adsorptive stripping voltammetry (DP-AdSV) and RSD < 3% ( N. = 7) for the square wave adsorptive stripping voltammetry (SqW-AdSV), and low limit of detection: LOD = 12.10-9 M ≈ 0.6 ppb (at a deposition potential ( E. )-800 mV和沉积时间( T. )50 s)和lod = 2.10-9 M ≈ 0.1 ppb (at E.  = −800 mV and T.  = 160 s) for the DP-AdSV and SqW-AdSV, respectively. This method has been successfully applied to analyze chromium in natural water.
