Modified carbon-containing electrodes in stripping voltammetry of metals

Abstract

Papers dealing with modified electrodes made of carbon materials and composites for use in stripping voltammetry of metals have been reviewed. The review consists of two parts, of which the first considers applications of modified glassy carbon and carbon paste electrodes, while the second describes diverse modified carbon-containing composite and microscopic electrodes. Information about modifiers, electrode modification methods, conditions, and limits of detection of elements in different materials has been tabulated. The review covers 550 papers published in Russia and abroad between 1990 and the first half of 2007.

Raman, X‐Ray Fluorescence Spectroscopies and Graphene Oxide Modified Screen Printed Electrodes to Identify the Pigments and Earth Present in Ancient Leather Samples

“…The cationic form of some elements detected by XRF in our samples i.e. As(3 +); Cu(2 +); Zn(2 +) and Ca(2+), see Figure 2b, and anions, as Cl À ; OH À ; CN À ; etc., possibly contained in the leather samples, could interact with Fe(III) generating inner-sphere and/or outer-sphere more stable complexes, or hydroxide species [37,38]. All these compounds contribute to reduce the amount of free Fe(III) in the electrolysis solution.…”

Upstream microelectrodialysis for heavy metals detection on boron doped diamond

“…[18]. Carbone electrodes like graphite, glassy carbon, screen printed and carbon paste electrode are now more employed for a friendly environment monitoring to trace metal analysis [19,20].…”

Simultaneous Determination of Pb and Cd Traces in Water Samples by Anodic Stripping Voltammetry Using a Modified GC Electrode

“…They may enter the food chain and accumulate in marine plants to endanger organisms like mussels, clams or shrimp, which concentrate them [11,16]. Stozhko et al in their review paper [17] provided a detailed list of references regarding modified GC electrodes used in stripping voltammetry for determination of metals.…”
