anodic stripping voltammetry by derivative pulse polarography
1
differential pulse anodic stripping voltammetry, DPASV
an electrochemical technique where the analyte of interest is first electroplated onto the working electrode before being removed or 'stripped' by applying an oxidising potential (as a series of voltage pulses of increasing amplitude). During removal the cell current is measured as a function of time and as a function of the potential between the indicator and reference electrodes. The current is sampled before and after each voltage pulse.
