“…Among these techniques, voltammetry is a sensitive, cheap and versatile choice, especially when it includes analyte preconcentration by reduction (anodic stripping voltammetry, ASV) or by adsorption (adsorptive stripping voltammetry, AdSV) [7]. For a long time, stripping voltammetric measurements were mostly carried out with mercury drop or mercury film electrodes [8]. However, in the last years, the toxicity of mercury has encouraged its replacement by alternative materials such as bismuth and antimony films on carbon supports or conventional solid electrodes chemically modified with nanoparticles and molecules having some affinity for heavy metals [9][10][11].…”

Abstract:The influence of the experimental conditions (glutathione concentration and incubation time and temperature) concerning the covalent immobilization of glutathione via carbodiimide coupling on the behavior of a glutathione modified screen-printed carbon electrode obtained by electrografting is evaluated. The optimized parameters fasten the modification process and improve the performance of the sensor as compared to the usual procedure. This suggests the convenience of a tailored preparation of metal sensors based on metal-binding biomolecules such as glutathione.

“…The performance of voltammetry is strongly influenced by the working electrode material. For many years, electrochemical stripping methods were associated with the use of working mercury electrodes for the determination of trace metal ions due to the extensive cathodic potential range [3]. However, mercury is toxic and poses a significant health and environmental hazard.…”

This work describes the immobilization of 4-carboxybenzo-18-crown-6 (CB-18-crown-6) and 4-carboxybenzo-15-crown-5 (CB-15-crown-5) assisted by lysine on aryl diazonium salt monolayers anchored to the surface of graphite-epoxy composite electrodes (GEC), and their use for the simultaneous determination of Cd(II), Pb(II) and Cu(II) by differential pulse anodic stripping voltammetry (DPASV). These modified electrodes display a good repetitivity and reproducibility with detection and quantification limits at levels of µg L -1 (ppb), confirming their suitability for the determination of Cd(II), Pb(II) and Cu(II) ions in environmental samples. The overlapped nature of the multimetal stripping measurements was resolved by employing the two-sensor array CB-15-crown-5-GEC and CB-18-crown-6-GEC, since the metal complex selectivity exhibited by the considered ligands could add * e-mail: manel.delvalle@uab.es; Phone: (+34) 93 581 10 17; Fax: (+34) 93 581 24 77 *Manuscript This is the author's version of a work that was accepted for publication in Talanta (Ed.

“…However, mercury is still one of the most commonly used electrode materials due to its excellent electrochemical properties, e.g., high hydrogen overvoltage and renewal of the working surface after every analysis by a new drop. However, it has also some disadvantages such as poor mechanic stability and the toxicity of the liquid mercury (Barek et al 2001). The silver 85 solid amalgam electrode (AgSAE) represent an intermediate step between mercury and solid electrodes and combine their advantages (Novotný and Yosypchuk 2000;Barek et al 2006;Yosypchuk and Barek 2009).…”
