The electrochemical behaviour of ebastine was studied at hanging mercury drop electrode using cyclic voltammetry and differential pulse voltammetry. The molecule shows a single, well defined reduction peak due to the reduction of carbonyl group. The voltammetric conditions were optimized with respect to maximum peak signals. The linearity between the peak signal and the concentration of ebastin...

Pyranine as a new class of fluorescent chemosensor for the Cu(+) ion is reported. The probe is capable of discriminating ranges of cations from the Cu(+) ion, even in competing environment. The dye displayed a rapid fluorescence response (t1/2 = 1.66 min) towards the Cu(+) ion, and the micromolar detection limit enabled the detection of the ion in environmental samples. The observed stoichiomet...

Purpose: A new sensitive sensor was fabricated for the determination of ivabradine hydrochloride (IH) based on modification with multiwalled carbon nanotubes using sodium dodecyl sulfate as micellar medium to increase the sensitivity. Methods: The electrochemical behavior of IH was studied in Britton-Robinson buffer (pH: 2.0-11.0) using cyclic and differential pulse voltammetry. Results: The vo...

Nitrogen doped diamond-like carbon thin films with or without platinum and ruthenium incorporation (N-DLC or PtRuN-DLC) were deposited on highly conductive p-Si substrates by DC magnetron sputtering to study the effect of Pt and Ru doping on the voltammetric performance of the N-DLC films. The potential windows of these film electrodes were measured in different electrolytic solutions, such as ...

Granisetron showed one well-defined reduction peak at Hanging Mercury Drop Electrode (HMDE) in the potential range from -1.3 to -1.5 V due to reduction of C=N bond. Solid-phase extraction technique was employed for extraction of Granisetron from spiked human plasma. Granisetron showed peak current enhancement of 4.45% at square-wave voltammetry and 5.33% at cyclic voltammetry as compared with t...

The surface of indium-tin oxide (ITO) substrates was successfully modified with aziridine. Modification of the surface was achieved through facile ring-opening, and hyperbranching polymerization of the ring-strained heterocycle initiated from the reactive group on the surface. Amine density of the aziridine-modified ITO measured with UV-vis spectrophotometry is 10 amines/nm2. Cyclic voltammetri...

Many quinolones, substituted quinolines and thiones are well known for their biological activity. The redox characteristics of such biological substances may provide valuable information about the redox behaviour in living systems. The present paper is aimed at carrying out a methodical cyclic voltammetric investigation of the peak potential values of 4-methyl/phenyl -3vinyl quinoline-2(1H) one...

In this communication, nickel diselenide (NiSe2) nanoparticles are synthesized by a facile and low-cost hydrothermal method. The synthesis method can be extended to other metal diselenides as well. The electrode made of NiSe2 exhibits superior electrocatalytic activity in the hydrogen evolution reaction (HER). A low Tafel slope of 31.1 mV per decade is achieved for NiSe2, which is comparable to...

Cyclic voltammetric (CV) and chronoamperometric (CA) behaviors of 1,3,5-triphenylformazan (TPF), 3-(p-nitrophenyl)-1,5-diphenylformazan (PNF) and 3-(m-nitrophenyl)-1,5-diphenylformazan (MNF) were studied in dimethyl sulfoxide medium. TPF was found to give a single sharp cathodic CV peak corresponding to a gain of one-electron per molecule. The diffusion coefficient and the number of electrons t...
