A stannum/bismuth/poly(p-aminobenzene sulfonic acid) film electrode for measurement of Cd(II) using square wave anodic stripping voltammetry

Development of a novel cyano group containing electrochemically deposited polymer film for ultrasensitive simultaneous detection of trace level cadmium and lead

“…This may be probably due to the additional presence of CN groups in the film. Also, P(DPA-co2ABN)/GC-ME exhibited much lower LOD and wider concentration range for Cd 2+ and Pb 2+ than reported in the literature for other PANI/PANI derivative based modified electrodes, such as poly(ANI-co-DDS) [52], Bi/PANI/GC [53], Bi/poly(p-ABSA)/GC [54], Bi/Sn/poly(p-ABSA)/GC [55], Bi/Nafion/thiolated PANI/GC [56], Bi/PANI/GC [20] and PANI/GC [47] (Table 2). Oztekin et al [57] reported the use of poly(1,10-phenanthroline) (PP) modified GC for electrochemical determination of Cd 2+ ions.…”

A novel conducting poly(p-aminobenzene sulphonic acid)-based electrochemical sensor for sensitive determination of Sudan I and its application for detection in food stuffs

“…Considering the active sites of poly(p-ABSA) film bind strongly with analytes, it was necessary to polish the electrode and construct a new film after each analysis in order to obtain a polymer film with good stability, more active sites, and good reproducibility (Xie et al, 2010;Xiong et al, 2011). The reproducibility of the poly(p-ABSA)/GCE was estimated by comparing the oxidation peak current of a constant Sudan I concentration.…”

“…Poly(p-aminobenzene sulphonic acid) (poly(p-ABSA)) modified electrodes have been employed in recent years (Chen et al, 2010;Wu, Li, & Luo, 2008;Xie, Luo, & Li, 2010;Xiong, Luo, & Li, 2011) because the polymer film has some excellent characteristics including stability, more active sites, reproducibility and homogeneity in electrochemical deposition, and it can adhere strongly to the electrode surface (Jin et al, 2008). There are large numbers of p-p bonds, electron-rich N atoms, and high electron density among sulphonic group in poly(p-ABSA) film.…”

Rapid and sensitive determination of cobalt by adsorptive cathodic stripping voltammetry using tin–bismuth alloy electrode

“…It offers the closest behavior to mercury but with very low toxicity. Both in situ or ex situ bismuth film electrode [21,22], bismuth bulk electrode (BiBE) [23,24], and tin-bismuth film electrode [25] display an attractive stripping behavior. However, the bismuth bulk electrode is complicated to be fabricated due to the fragileness of the bismuth.…”
