The voltammetric performance of edge-plane pyrolytic graphite (EPG) electrode via adsorptive stripping voltammetry was investigated for study of the electrochemical behavior of omeprazole (OMZ) in aqueous solution. The results revealed that the oxidation of OMZ is an irreversible pH-dependent process that proceeds with the transfer of one electron and one proton in an adsorption-controlled mech...

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...

Determining the geochemistry in the remote hostile Martian environment requires sensors specifically designed to meet such a unique challenge. We report here on the initial development, considerations, and a prototype array of electrochemical sensors for measuring in-situ a variety of ionic species in the Martian soil (regolith). The sensor array consists mainly of potentiometric ion selective ...

The electrocatalytic activity of an N,N-diethylaniline-grafted carbon (DEA/PFC) electrode was utilized to improve the sensitivity in the cathodic detection of free chlorine. Voltammetric curves showed a well-defined cathodic peak of free chlorine on DEA/PFC, lowering the overlap with that of dissolved oxygen. Amperometric measurements were applied for the determination of free chlorine for a co...

A robust voltammetric method has been developed and validated for the determination of Fe(II) and Fe(III) in pharmaceutical iron polysaccharidic complexes. Undesirable low molecular weight iron complexes, at concentration about 3% in the pharmaceutical formulation, can be easily determined with good accuracy and precision. This methodology can be proposed as a viable, environmentally sustainabl...
