Abstract

This text will introduce the main voltammetric methods of analysis, from its basic aspects to applications in trace analysis. The techniques to be presented are continuous current (polarographic; DC, direct current), sampled direct current (sampled DC), normal pulse (NP, normal pulse), differential pulse and square wave voltammetry. The use of voltammetry in trace analysis is discussed using anodic / cathodic stripping and adsorptive stripping voltammetry. Aspects related to the matrix effects and to method validation will also be discussed.

Keywords
