Electrochemical System for Determination of Esmolol Hydrochloride Using Square Wave Adsorptive Stripping Voltammetry

open access: yesInternational Journal of Electrochemical Science, 2016
A simple, validated, sensitive and reliable electrochemical method for determination of esmolol hydrochloride (ESM) has been described. The cathodic behavior of ESM onto a hanging mercury drop electrode (HMDE) was evaluated using phosphate buffer of pH 7.

Adsorptive stripping voltammetry of riboflavin by square wave polarography.

open access: yesNIPPON KAGAKU KAISHI, 1989
Two stripping methods of analysis of riboflavin were proposed by square w ave polarography in which preconcentration is achieved by the adsorption of riboflavin or its reduced form. The supporting electrolyte used was O.1 M ammonium acetate, the preconcentration potentials were -O.65 V (anodic stripping) and 0 V (cathodic stripping).

Determination of tryptamine in foods using square wave adsorptive stripping voltammetry

open access: yesTalanta, 2016
Tryptamine, a biogenic amine, is an indole derivative with an electrophilic substituent at the C3 position of the pyrrole ring of the indole moiety. The electrochemical oxidation of tryptamine was investigated using glassy carbon electrode (GCE), and focusing on trace level determination in food products by square wave adsorptive stripping voltammetry (
