- 01 Jan 2002
TL;DR: In this article, the problems associated with applying voltammetric techniques to the analysis of biologically relevant organics within complex media are identified and, through reviewing the very recent literature (1999-mid-2001), possible solutions are described.

Electrochemical detection of aniline: an electrochemically initiated reaction pathway
TL;DR: By varying oxidation times of the catechol species or by increasing the number of repetitive voltammetric scans from one to four the analytical parameters can be improved and provide a linear detection range for aniline with a corresponding limit of detection.

Sonoelectrochemically enhanced determination of 5-aminosalicylic acid
TL;DR: The introduction of ultrasound is shown to significantly enhance the oxidation signal intensity thereby enabling the detection of low concentrations with the linear range (1-57 muM) adequate for assessing free drug within physiological samples.

Voltammetric investigation of hair dye constituents: application to the quantification of p-phenylenediamine
TL;DR: The nature of the electrode response was characterised and issues of surface fouling resulting from the deposition of electrogenerated reaction products were addressed.

Bioanalytical utility of sonovoltammetry
TL;DR: Dopamine dissolved within egg homogenate was used as a model system to study the effects of electrode contamination and its subsequent reactivation through ultrasonically mediated in situ cleaning effects and the problem of retaining selectivity in the presence of high concentrations of ascorbate.
