“…A polymer film is often used to protect the electrode surface from organic substances present in natural samples that adsorb at the electrode surface in this way diminishing the response to analyte [2,36,37]. It was found that the Nafion coating improves the response of Zn(II) and Cu(II) at low Triton X-100 concentrations.…”

“…Such a positive surfactant effect might be due to an improvement of the preconcentration of these metals by complexation with the surfactant at higher concentrations. A positive surface active compound effect has been obtained before only at mercury film electrodes (MFE) coated with polymer films, in particular for Pb(II) [2].…”

“…1 Apesar disso, devido à alta toxicidade do mercúrio, diversas alternativas têm sido propostas a fim de substituir estes eletrodos por outros de menor toxicidade. [1][2][3] Desta maneira, vários materiais eletródicos como cobre, ouro, irídio, rutênio, bismuto, antimônio, pasta e compósitos à base de carbono, entre outros, vêm sendo investigados para serem aplicados como eletrodos sólidos em substituição aos eletrodos de mercúrio. 2 A principal característica desejável para estes materiais é que apresentem um desempenho melhor ou semelhante ao eletrodo de mercúrio, principalmente quanto a sua robustez e intervalo de potencial negativo de trabalho.…”

“…The hanging mercury drop electrode (HMDE) or the mercury film electrode have been commonly used for the sensitive detection of the above element by means of the ASV technique [2,3]. Unfortunately, the ASV curves of copper in the vast majority of the supporting electrolytes are partly overlapped by the current from the anodic dissolution of mercury,…”
