Review of Electroanalytical-Based Approaches for the Determination of Benzodiazepines

open access: yesBiosensors, 2019
The benzodiazepine class of drugs are characterised by a readily electrochemically reducible azomethine group. A number are also substituted by other electrochemically active nitro, N-oxide, and carbonyl groups, making them readily accessible to ...

Determination of Secnidazole in Urine by Adsorptive Stripping Voltammetry.

open access: yesChemical and Pharmaceutical Bulletin, 2000
Cyclic voltammetry was used to explore the adsorption behavior of secnidazole on a hanging mercury drop electrode (HMDE). The effects of various operational parameters on the accumulation behavior of the adsorbed species were tested. Thus, a sensitive stripping voltammetry procedure for the determination of secnidazole with an adsorptive accumulation ...
