Detection of trace levels of Pb2+ in tap water at boron-doped diamond electrodes with anodic stripping voltammetry

Application of Modified Tafel Analysis to the Identification of Corrosion Products on Archaeological Metals Using Voltammetry of Microparticles

“…Additionally, it should be noted that in our case, copper is the first metal deposited during the experiment. It is known that copper deposition notably influences the deposition of other metals like Cd [68], Pb [69] and Zn [70] as a result of the formation of intermetallic compounds and often by appearance of a misleading extra peak due to hydrogen evolution at freshly exposed copper under stripping conditions at low pH values [71]. For instance, metal-metal interaction during stripping experiments results in the drop of peaks for cadmium and zinc when copper was added [72].…”

Determination of Lead by Square Wave Anodic Stripping Voltammetry Using an Electrochemical Sensor

“…Furthermore, future regulations may severely restrict the use of Hg as a modified material because of its unavoidable toxicity. Alternative electrode materials, such as carbon-based, 8 composite materials, 14,15 boron-doped diamond 6,10 or bi-modified electrodes, [16][17][18] have been explored, but both the low potential limit and sensitivity of the anode make these materials undesirable as reusable sensors because some heavy metals fuse with these electrode materials. 2 In particular, when bismuth film electrodes were applied for in situ monitoring, interference from naturally occurring water easily led to irreproducible measurements at pH levels above 4.0.…”

“…However, these methods are expensive and require long analysis times, which are not suitable for in situ environmental screening analysis. 6 Alternatively, anodic stripping voltammetry (ASV) is commonly employed to detect Pb 2+ , which can be accumulated onto the electrode surface and stripped off voltammetrically or chronopotentiometrically. [7][8][9][10] ASV possesses a low detection limit, a wide measurement range, and the capability for multi-ion analysis; ASV has been conducted for heavy metal measurements on various working electrodes and sensors and has shown great potential for practical applications.…”

Square Wave Voltammetry for Analytical Determination of Cadmium in Natural Water Using Ca10(PO4)6(OH)2-Modified Platinum Electrode

“…More specifically, the electrochemical detection of heavy metals has been performed on different electrode surfaces, including solid electrodes [8,9], Nafion-modified electrodes, [10] and microeletrodes [11]. Several researchers have reported the use of chemically modified electrodes (CMEs) in electroanalysis, using pulse techniques such as square-wave voltammetry, and differenttial pulse voltammetry [12].…”
