Adsorptive stripping voltammetry in trace analysis
In trace analysis the voltammetric stripping methods are popular because of their sensitivity — ranging down to sub ppb concentration. These methods are accurate and precise and the instrumentation is of low cost. The stripping methods are based on previous accumulation of the ion or compound to be determined on the working electrode. In addition to the electrolytical accumulation — used in anodic or cathodic stripping voltammetry (ASV or CSV resp.) also adsorptive accumulation of the species on the working electrode can be exploited, as many organic compounds exhibit surface active properties that are manifested by their adsorption from solution onto the surface of the solid phase.
