Abrasive stripping voltammetry — Technique where traces of solid particles are abrasively transferred onto the surface of an -> electrode, followed by an electrochemical dissolution (anodic or cathodic dissolution) that is recorded as a current-voltage curve [i]. It allows qualitative and quantitative analysis of metals, alloys, minerals, etc. The technique is a variant of - voltammetry of immobilized particles [ii]. 

Since its introduction in 1989 [3,4], the voltammetry of (immobilized) microparticles (earlier termed abrasive stripping voltammetry) has attracted considerable attention and initiated a wide range of experimental and theory-based studies. As outlined in Section 6.1, the first decade of investigations has been vell reviewed [5-8], while a recent monograph [9] has included the details of any diverse applications up until late 2004. Consequently, whilst the following sections will focus on the period between 2005 and the present, any earlier contributions deemed relevant to an understanding of the current investigations will also be cited or discussed.

Cepria and coworkers used the voltammetry of immobilized microparticles to detect and quantify the cadmium pigments (e.g., cadmium sulfide and cadmium sulfoselenide) used in artists paints, as well as in glasses, plastics, ceramics, and enamels [141]. For this, a simple, fast and reliable technique was developed that proved to be especially applicable for valuable art objects, as it was minimally invasive and required only nanogram quantities of material (see also Section 6.4.1). For quantification purposes, an abrasive stripping scan was used from + 0.3 V to —1.0 V, following a 10 s pre-treatment step at —1.5 V. The Cd oxidation peak was evaluated with respect to an internal AgCl calibration standard.
