Electrochemical Determination of Catechol Using a Disposable Printed Electrode with Conductive Ink Based on Graphite and Carbon Black

Analytica—A Journal of Analytical Chemistry and Chemical Analysis, Journal Year: 2024, Volume and Issue: 5(2), P. 250 - 262

Published: June 1, 2024

Catechol (CT) is a phenolic compound widely used in various industrial sectors, but it toxic; thus, there need for methods that aim to identify and quantify the existence of residues this material environment. In study disposable printed electrochemical sensor was developed as an effective alternative determining CT water samples. The electrode, called SPEC, manufactured using screen-printing method polyethylene terephthalate (PET) support, which conductive ink based on carbonaceous materials print working auxiliary electrodes silver/silver chloride reference electrode. optimal ratio 6.25% carbon black, 35.42% graphite, 58.33% nail polish. obtained characterized by scanning electron microscopy (SEM). assessment effect pH redox process showed Nernstian behavior (0.057 V pH−1), indicating involves same number protons electrons.

An Affordable and Efficient Graphite‐Coated Electrode for the Voltammetric Determination of Catechol

ChemistrySelect, Journal Year: 2024, Volume and Issue: 9(20)

Published: May 22, 2024

Abstract An affordable and highly efficient graphite‐coated electrode was developed applied in this work as a compelling alternative to other modified electrodes catechol determination. Electrode modification involved simple deposition process using commercial graphite dispersion, Aquadag®Acheson. Morphological electrochemical studies revealed the formation of uniform layer with enhanced surface area significant conductivity. Catechol quantification successfully achieved linear concentration range extended up 80 μmol L −1 detection limit 0.5 under optimized conditions (pH 7 an accumulation time 2 min). Spike‐and‐recovery experiments validated accuracy Unlike hydroquinone, structurally similar compounds such phenol resorcinol did not interfere analysis. The interference posed by hydroquinone addressed derivative treatment voltammograms allowing peaks resolution.
