Electroanalytical methods

Electroanalytical method refers to a scientific approach that involves the measurement of electrical quantities such as current or potential and their correlation with chemical parameters. This method is concerned with the interplay between electricity and chemistry and is advantageous due to its ease of use, minimal processing steps, short determination times, and lack of pretreatment requirements.From: Handbook of Pollution Control and Waste Minimization [2019], Electrochemical determination of 8-hydroxyquinoline in a cosmetic product on a glassy carbon electrode modified with 1-amino-2-naphthol-4-sulphonic acid [2021]

Due to the possibility of preconcentrating the analyte onto the working electrode (by factors of 100 to more than 1000), stripping analysis has the lowest limits of detection of all electroanalytical methods (i.e., 10−11 M). Of no less importance are its wide linear dynamic range, its ability to analyze more than one analyte (four to six) at a time, and its relatively low cost. Hence, stripping analysis is ideally suited forThe determination of chemical species at trace levels in complex samples of environmental, clinical, food, pharmaceutical, or industrial originTrace metal speciation in natural waters or in situ field screeningOn-line, high-throughput screening applications

In the literature, the determination of 8-hydroxyquinoline has been reported by various analytical methods such as thin-layer chromatography,[16] flow injection spectrophotometry[17] and high-performance liquid chromatography.[18–20] Compared to the analytical methods mentioned above, electrochemical procedures are environmentally friendly and cost-effective. Also, electroanalytical methods do not require pretreatment and offer advantages such as ease of use, few processing steps and short determination times.[21]
