Oxidation of formaldehyde (HCHO) is very important, owing to its use in fuel cells. Modification of electrodes surfaces is an excellent way to decrease the overpotentials as well as to increase the current density of the voltammetric response.pt as most efficient metal catalyst can easily be poisoned by product of oxidation and also it has high cost. In this work an efficient and low cost elect...
In this research, quantities of carbon nanospheres (CNSs) were prepared with a convenient and low cost method at atmospheric pressure and functionalized with the xanthate group in a simple way. The materials were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectra (FT-IR), and X-ray photoelectron spectroscopy (XPS). In addition, the c...
developing simple, sensitive and selective sensing systems for dopamine is important due to its biological significance. in this work, a silver nanoparticles-modified carbon paste electrode (agnps-cpe) has been constructed and used to detect of dopamine (da) in the simultaneous presence of ascorbic acid (aa) and uric acid (ua) at neutral ph 7.0 by cyclic voltammetry. the modified electrode show...
In this article, the electrochemical behavior of triethanolimine is described with a carbon paste electrode. A differential pulse voltammetric method was also developed for the determination of triethanolamine as an application to electroanalysis at a carbon paste electrode. The resultant voltammograms have revealed the irreversible electrochemical process that can be utilized to quantify the s...
