As (III) was determined by differential pulse polarography (DPP) in 1 mol L-1 HCl as supporting electrolyte. For quantification, the -0.35 V peak (versus Ag/AgCl) was chosen. The obtained detection and quantification limits ...

The interaction of glutathione with four β-lactam antibiotics was studied by an AC polarographic procedure. The interaction stability constant and the coordination number were calculated from the AC polarographic data. The ...

The amphetamine derivative 4,5‐dimethoxy‐2‐nitrophenyl‐2‐aminopropane, a positional isomer of the potent hallucinogen DON, was studied by cyclic voltammetry and polarography. The nitro compound was reduced to the corresponding ...

Electrochemical reduction of Ketanserin was studied at different pH and concentrations using polarography and cyclic voltammetry. Ketanserin exhibits two differential pulse polarographic peaks at the dropping mercury ...

Loratadine, a potent antihistamine drug, is not directly electroreducible at a dropping mercury electrode; however, by means of a nitration procedure it is possible to obtain a nitro-loratadine derivative which has been ...

The electroactivity of a degradation product from penicillin V is described.This electroactive product is formed by acidic hydrolysis at pH 4.0 and heating at 90QC for 60 minutes. This derivative has not been identified, ...

The isolation and identification of a cathodic degradation product from cephradine after acidic hydrolysis in presence of 1 % formaldehyde is reported. Also, the electroacti vity of an anodic degradation product is described. ...

Cephalexin was found to be polarographically reducible after hydrolysis in an acidic medium, producing two polarographic waves. Both waves were diffusion controlled. The concentration‐diffusion plot method was used for the ...
