Mercury film nickel minigrid optically transparent thin layer electrochemical cell

Differential pulse anodic stripping voltammetry in a thin-layer electrochemical cell

“…The detection limit of 10 ng/ml for lead and cadmium is more than two orders of magnitude less than that previously reported by thin-layer coulometry (1)(2)(3)(4)(5)(6). In addition to good sensitivity, a linear relationship between peak current and concentration was obtained over a wide concentration range.…”

A spectroelectrochemical approach to the electrodeposition of bismuth film electrodes and their use in stripping analysis

“…Moreover, spectroelectrochemistry has proven to be useful for quantification via both electrochemical and spectroscopic principles. Some of the spectroelectrochemical studies have been performed with optically transparent electrodes (OTEs), such as metal minigrids with mercury thin films plated on them [16,17] or indium tinoxide (ITO) electrodes where the chemical compounds are directly deposited on them [18][19][20]. In contrast, other spectroelectrochemical stripping experiments have been carried out with solid electrodes such as glassy carbon electrodes [21][22][23].…”

“…In contrast, other spectroelectrochemical stripping experiments have been carried out with solid electrodes such as glassy carbon electrodes [21][22][23]. Depending on the electrode, different light beam configurations can be used, such as normal incidence to an OTE [16,17], attenuated total internal reflectance [18][19][20], or parallel incidence to the working electrode surface [21][22][23]. Until now, stripping spectroelectrochemistry has been applied to determination of toxic heavy metals, including their mixtures, namely copper [21,22], lead and cadmium [18], mercury and lead [19], or cadmium and copper [20].…”

Electrochemical and spectroscopic studies of some less stable oxidation states of selected lanthanide and actinide elements

“…Porous metal foam (Astro Me t As sociates , Cincinnati, OH) was ob tained as the copper and nickel material (series 280-5 ) in bulk sh eets which were sect ioned into electrodes between 3 and 5 mm th ick. The PMF wa s electroplated wi th Pt , by the Oak Ridge Gaseous Diffusion Plant , using a proprietary process , or with Au , by ORNL using the Sel-Rex process , or was amalgamated 27. Electrode coverage was checked by vol tammetry.…”
