“…Amounts of acrylamide were measured by square-wave voltammetry in potato chips (Zargar et al 2009). Recently, a new approach to electrochemical determination of AA was published (Veselá and Šucman 2013). In this study the use of adsorptive differential pulse voltammetry for determination and quantification of the AA content in food and feedstuff was described.…”

Acrylamide is considered to be an endogenous contaminant of food and feedstuff. Attention is paid to the acrylamide content in human nutrition products; however, there is lack of data about its concentrations in feedstuff. The aim of this study was to use a newly developed adsorptive stripping voltammetry procedure for determination of acrylamide concentrations in five and three different kinds of dog and cat dry feedstuff, respectively. The applied analytical procedure consists of a solvent extraction in ultrasound bath, followed by voltammetric measurement at the hanging mercury drop electrode in ammonia buffer. The accuracy of the method was verified by use of standard reference materials. The range of acrylamide concentration found in samples of dry dog and cat feedstuff ranged from 106 to 358 μg/kg, and from 66 to 269 μg/kg, respectively. The precision of analyses expressed in form of the relative standard deviations ranged between 0.6-1.7%. The voltammetric procedure appears to be a reliable, sensitive, rapid and low-cost analytical technique for the determination of acrylamide in food and feedstuff. The concentrations of acrylamide found in feedstuff were relatively moderate but it is undoubtedly necessary to monitor its concentrations in future.

“…Most analytical protocols for determining organic compounds involve adsorptive accumulation of the analyte. Such analytes include the active ingredients of various pharmaceuticals, organometallic compounds, pesticides and herbicides, food colourants, explosives and emerging contaminants, for example acrylamide 195 , carcinogens 194 and cannabis 196 . ESA is typically conducted in aqueous solutions 5,21 , but can also be performed in nonaqueous media such as acetonitrile with tetrabutylammonium salts for the determination of explosive materials, for example TNT 197 .…”

Electrochemical stripping analysis (ESA) is a trace electroanalytical technique for the determination of metal cations, inorganic ions, organic compounds and biomolecules. It is based on a pre-concentration step of the target analyte(s), or a compound of the target, on a suitable working electrode. This is followed by a stripping step of the accumulated analyte using an electroanalytical technique. Advantages of ESA include high sensitivity and low limits of detection, multi-analyte capability, low cost of instrumentation and consumables, low power requirements, potential for on-site analysis, speciation capability and scope for indirect biosensing. This Primer covers fundamental aspects of ESA and discusses methods of pre-concentration and stripping, instrumentation, types of working electrodes and sensors, guidelines for method optimization, typical applications, data interpretation and interferences, and method limitations and workarounds. Finally, the current trends and future prospects of ESA are highlighted.
