Antimony-based electrodes for analytical determinations
TL;DR: Antimony film electrodes (SbFEs) as mentioned in this paper offer some interesting characteristics such as favorably negative overvoltage of hydrogen evolution, wide operational potential window, convenient operation in acidic solutions of pH 2 or lower and a small Sb stripping signal.

Amir M. Ashrafi,Sandra Cerovac,Sanja Mudrić,Valéria Guzsvány,Lenka Husáková,Iva Urbanová,Karel Vytřas +6 more
TL;DR: In this paper, a nanocomposite based on multiwalled carbon nanotubes (MWCNT) modified with antimony nanoparticles (SbNPs) was synthesized chemically and has been applied to construct an electrode using carbon paste as substrate, which was applied for the determination of trace heavy metals Pb2+ and Cd2+ by square wave adsorptive stripping voltammetry.

Selective voltammetric determination of Cu(II) based on multiwalled carbon nanotube and nano-porous Cu-ion imprinted polymer
TL;DR: In this paper, a very high selective Cu-ion imprinted polymer as a chemical modifier was prepared by formation of 1-(2-pyridylazo)-2-naphthol complex for stripping voltammetric determination of copper.

Bismuth-coated carbon electrodes for anodic stripping voltammetry
TL;DR: Stripping voltammetric measurements of microgram per liter levels of cadmium, lead, thallium, and zinc in nondeaerated solutions yielded well-defined peaks, along with a low background, following short deposition periods, indicating great promise to centralized and decentralized testing of trace metals.

Insights into the anodic stripping voltammetric behavior of bismuth film electrodes
TL;DR: In this paper, the bismuth-coated electrode is shown to be prone to errors caused by the formation of Cu-Zn intermetallic compound, that can be circumvented by the addition of gallium, in a manner analogous to mercury film electrodes.
