Abstract

As part of an ongoing investigation into arsenic (As) analysis by anodic stripping voltammetry (ASV), it was found that strong rinsing regimes in between samples could reduce the cumulative effect of organic and sulfide interferences. Longer term effects of this rinsing procedure on the measurement response have been investigated and the procedure optimized to give more a stable response over multiple sample analyses.
