“…A brownish film is observed on the working electrode. The usage of inorganic salts such as zinc sulfate, calcium chloride as supporting electrolyte at room temperature has been reported [17,18]. In the current study the effect of supporting electrolytes 0.5 M CaCl 2 and ZnSO 4 in the electropolymerization of DAP is then investigated.…”

A composite graphite (CG) electrode modified with poly(2,6-diaminopyridine) (PDAP) was used as solid state-ion selective electrode for determination of mercury. The electrooxidation of monomer 2, 6 diaminopyridine (DAP) onto CG was accomplished from the 30 mM DAP in 5% H 2 SO 4 and 0.5 M ZnSO 4 . The electrode displayed Nernstian response with slope of 28.4 AE 1 mV decade À1 in concentration range of 1 Â 10 À6 to 1 Â 10 À1 M and in solution of pH 3 -5. The limit of detection for electrode was 3 Â 10 À8 M with response time of 25 s. The electrode was also suitable as an indicator electrode in the potentiometric titration of Hg 2þ with iodide.

“…The EDX results analysis of Figure 4B show that electrosynthesized with CaCl 2 has 44.85% carbon (C) and 13.16% nitrogen (N). By comparison the electropolymerization of the PDAP is more disperse and uniform than the PANi and PPY [17,18]. For a solid state or coated wire Scheme 1.…”

Ferric Reducing Antioxidant Power (FRAP) assay is a measure of assessment of the total antioxidant power of compounds. In this study, the ability of homo and copolymer of Aniline (Ani) and Pyrrole (Py) to act as an antioxidant on ferric ion reduction is investigated. The oxidative homo and copolymerization on composite 2B pencil graphite were accomplished in citric acid medium containing calcium chloride (CaCl 2) as the supporting electrolyte by cyclic voltammetry method. The morphology and structural analysis of homo and copolymer was confirmed by SEM and FTIR. The FTIR and UV-visible spectra indicated that the increase of aniline monomer in the copolymer chain enhances the ferric ion reduction ability. The electrochemical impedance spectroscopy (EIS) is used for further investigation. It was revealed that the increase of aniline ring in polymeric chain decreased the charge transfer resistance (Rct) and thus increases the reduction effect and improved the free radical scavenging activity of copolymers.

The electrooxidation of several fuel compounds was studied using metallic nanoparticles of Au, Pd, Pt, AuPd and AuPt synthesized by direct electrodeposition by applying a constant potential of ‐200 mV (vs. Ag/AgCl) to pencil graphite in an acidic medium. Scanning electron microscope (SEM) images and X‐ray diffraction (XRD) data show that monometallic (Au, Pd and Pt) and alloys of bimetallic nanoparticles of AuPd and AuPt have been formed. The catalytic performance of the prepared electrodes was investigated in a neutral medium (100 mM phosphate buffer, pH 7) by cyclic voltammetry. Amongst all fuels, the highest current densities were obtained by the electrooxidation of formic acid (ca. 9.8 mA cm−2) and formaldehyde (ca. 9.7 mA cm−2) on the AuPt catalyst.
