A comparison of boron-doped diamond thin-film and Hg-coated glassy carbon electrodes for anodic stripping voltammetric determination of heavy metal ions in aqueous media

Determination of trace heavy Metals by Sequential Injection-anodic Stripping Voltammetry using Bismuth Film Screen-printed Carbon Electrode

“…Because of the toxicity of mercury and environmental regulations, however, mercury-free electrodes were developed. 2,[13][14][15] One of environmentally friendly electrodes, which is comparable to mercury electrodes, is the bismuth-film electrode (BiFE), as pioneered by Wang and coworker. 16 Its attractive properties include high sensitivity, well-defined and highly reproducible stripping signal, good resolution of neighboring peaks, low background characteristics, a large cathodic working potential range, and being insensitive to dissolved oxygen, which eliminates the time-consuming de-oxygenation step.…”

“…An additional advantage of ASV over AAS, ICP-AES or ICP-MS is simplicity of the instrumentation, which is relatively inexpensive, requires low electrical power and low maintenance, and is portable as well as suitable for automation. [1][2][3][4] Combining stripping voltammetry with flow systems has significant advantages over batch analysis, such as a high level of automation, speed of analysis, improvement of accuracy and precision, less risk of contamination and cost-effective operation. [5][6][7][8] Sequential injection analysis (SIA) is one of the flow-analysis technique suited to stripping techniques that employ a preconcentration stage of the analyte on the working electrode before an actual measurement.…”

Determination of As(III) by anodic stripping voltammetry using a lateral gold electrode: Experimental conditions, electron transfer and monitoring of electrode surface

“…Many kinds of working electrode materials have been reported for the determination of arsenic, including platinum, gold, carbon substrates, and boron-doped diamond [11,12,20,28].…”

Fabrication and surface characterization of poly(4-aminodiphenylamine) film modified electrode and its application for lead and cadmium determination

“…The sensitivity of the present system given by the slope of the linear relationship of I p vs [M 2+ ] was compared with other electrochemical systems [36][37][38][39][40][41][42] and presented in Table 1.…”
