Electrochemical sensing of copper employing tellurium film electrode

Tellurium Film Electrodes Deposited on Carbon and Mesoporous Carbon Screen‐printed Substrates for Anodic Stripping Voltammetric Determination of Copper

“…The following commercial screen‐printed carbon electrodes produced by DropSens (Spain) were used: carbon (DRP‐C110), mesoporous carbon (DRP‐110 MC), ordered mesoporous carbon (DRP‐110 OMC), graphene (DRP‐110 GPH), graphene‐oxide (DRP‐110 GPHOX) and boron‐doped diamond (DRP‐BDD10). For comparison, a tellurium film electrode deposited on a GC support was also used .…”

“…To overcome the limitations associated with the location of the stripping signal of Cu outside the accessible potential windows of bismuth, antimony and tin film electrodes, we have recently proposed a new type of film electrode, namely, a tellurium film deposited on glassy carbon (TeF‐GCE) . We found that the TeF‐GCE yielded a relatively wide potential window (from −0.60 V up to +0.34 V), which ensures that the stripping peak of copper are well‐developed.…”

Photoactivity and optical applications of organic materials containing selenium and tellurium

“…1b). 50 The same group used the uorescent protein, TagRFP, linked to the PIM2 protein kinase analyte rather than the triplet sensitizer (11) and found that FRET was more efficient over a shorter distance, with the covalent linkage resulting in a smaller transfer distance. 51 In another study, Ligi et al conrmed that while the emission spectrum of the complex is dominated by the emission of the dye, the scale of its time-gated uorescence is determined by the persistence of the triplet state of the sensitizer.…”

“…[1][2][3][4][5] In the inorganic materials space, much work has focused on semiconductor lms or nanocrystals such as CdSe or PbSe quantum dots or CdTe. [6][7][8][9][10][11][12] In between lie classes of organochalcogens, where selenium and tellurium have been judiciously placed into otherwise organic materials. Such materials have been used as photovoltaics, 13 transistors, 14 thermoelectric generators, 15 light emitting devices, 16 and sensors.…”

Polyethylenimine Functionalized Multi‐walled Carbon Nanotubes for Electrochemical Detection of Chromium(VI)

“…Electrochemical technology has been one of the main techniques for analysis of Cr(VI), which is important to meet the ever-growing demando fo n-site high throughput detections.T he most widely appliede lectrochemical technique for chromium(VI) determinationi sc atalytica dsorptive stripping voltammetry (AdCSV), whichi so ften based on the preconcentration of Cr(VI) species on the electrode surface by using complexing agent [7][8][9][10].…”
