Novel method for standard addition signal analysis in voltammetry

Abstract

A new procedure for standard addition analysis in voltammetry based on the slope of the peak at the inflection point (SSAA) is proposed. It is fully automated and does not require any subjective user decisions. It has been tested for both simulated and experimental data. Experimental data included DPASV measurements of Pb(II) and Cd(II) on RAgABE, and Tl(I) on BiABE as a working electrode. In each case the procedure offered good accuracy, precision and perfect reproducibility.
