Voltammetric flow-injection determination of glucose in blood serum

A method for voltammetric flow-injection determination of glucose in blood serum is described by which the catalytic current associated with formation of the Fehling reactant on a metallic copper electrode is used as the analyte signal. The analyte signal is proportional to the concentration of glucose in the range of 1 × 10-4 - 1 × 10-3 M, and the throughput of the FIA system is 50 samples/h. The detection limit for determination of glucose is found to be 2 μg/ml. © 1999 Plenum Publishing Corporation

Voltammetric Behavior of Glucose and Other Carbohydrates on Metal Electrodes

The potential ranges of catalytic oxidation of glucose and some other carbohydrates on copper, silver, nickel, cobalt, and gold electrodes were determined, and possible schemes of electrochemical and chemical reactions were proposed. The ranges of the linear dependence of the current on the glucose concentration were established, and the possibility was shown of voltammetric determination of glucose in model solutions and human blood serum

Determination of uric acid by voltammetry and coulometric titration

Possible mechanisms of the electrochemical oxidation of uric acid at platinum, gold, graphite, and copper electrodes in a 0.5 M NaOH solution and phosphate (pH 6.86) and borate (pH 9.18) buffer solutions were considered. The stoichiometric coefficients in the reaction of boric acid with electrogenerated bromine and hypobromite ion were determined. Working conditions for the voltammetric determination of uric acid were selected and the detection limits for uric acid were found in model solutions and blood serum. © 2001 MAIK "Nauka/Interperiodica"

Voltammetric determination of sugar in wines and wine materials using a copper electrode

A method for voltammetric determination of sugar in wines and wine materials is described using a metallic copper electrode in a 0.5 M NaOH solution. The method is time-saving and shows a sufficiently high reproducibility (sr ≤ 0.04). © 1999 Kluwer Academic/Plenum Publishers

Coulometric determination of oxygen dissolved in polar organic compounds with electrogenerated copper(I) ions

The possibility of using coulometry for determining the oxygen dissolved in some organic solvents was studied. The conditions were selected and the method was developed for determining oxygen dissolved in polar solvents readily miscible with water. Determinations were performed in 1 M NH3 + 1 M NaClO4 + 0.01 M EDTA aqueous solutions using copper(I) ions electrogenerated from a metal electrode. © 1998 MAEe Cyrillic signK Hayκa/Interperiodica Publishing
