"Simultaneous Kinetic Spectrophotometric Determination Of 2-furfuraldehyde And 5-hydroxymethyl-2-furfuraldehyde By Application Of A Modified Winklers Method And Partial Least-squares Calibration"

Abstract: A method is described for the simultaneous determination of 2-furfuraldehyde and 5-hydroxymethyl-2-furfuraldehyde; based On their reaction by a modified Winkler's method. A comparative study of the results found using the kinetic curves registered at 550 and 585 nm, as analytical signals, has been performed, The data set of the kinetic curves at 550 nm was selected as the analytical signal, Partial least squares (calibrating for a single chemical constituent at a time: PLS-1) multivariate calibration was then applied for the determination, The proposed method was satisfactorily applied to the analysis of wines, spirits, fruit juices and honey.

"Determination Of 2-furaldehyde In Transformer Oil Using Flow Injection With Pulsed Amperometric Detection"
Analyst 1996 Volume 121, Issue 6 Pages 755-759

Abstract: Transformer oil was de-oxygenated and then pumped (0.3 ml/min) through one chamber of a macrodialyzer cell while a stream of 0.1 M NaOH/0.1 M NaClO4 (solution A) was pumped (0.3 ml/min) through the adjacent chamber. 2-Furaldehyde (I) was partitioned through a 0.45 µm Durapore membrane into solution A, which was then injected into a carrier stream of solution A for pulsed amperometric detection at a Pt working electrode. The calibration graphs were linear for 1-8 and 5-40 ppm I for carrier flow rates of 0.8 and 0.4 ml/min, detection potentials of -800 and -750 mV vs. SCE and injection volumes of 100 and 67 µL, respectively; the respective detection limits were 0.5 and 1 ppm I.

"Electrocatalysis And Amperometric Detection At A Ruthenium-modified Indium-hexacyanoferrate Film Electrode"
Electroanalysis 1998 Volume 10, Issue 17 Pages 1163-1167

Abstract: The electrocatalytic activity of a glassy carbon electrode modified with electrochemically deposited indium(III)-hexacyanoferrate (InHCF) film, which was subsequently cycled in a solution of Ru(III), is described. Although the resulting Ru-modified InHCF thin film electrode behaves in a manner analogous to the parent InHCF film, its stability was improved. Such a modified electrode was characterized, in acidic (pH 2) 0.5 M KCl solutions, by cyclic voltammetry, and FIA. It exhibits a high catalytic activity for the electrooxidation of some inorganic and organic compounds of anal. interest, such as As(III), S2O32-, cysteine, and 2-furaldehyde. The anal. applicability of this novel ruthenium-modified InHCF film electrode for the amperometric detection in flowing streams is discussed. Repetitive sample injections with amperometric detection of S2O32- at +0.8 V (vs. Ag/AgCl) as applied potential produced a stable response over 8 h of operation, making it very attractive for practical applications.

"Determination Of 2-furaldehyde By Flow Injection Analysis"
Quim. Anal. 1982 Volume 1, Issue 4 Pages 261-267
Alonso, J.;Bartroli, J.;Blanco, M.

Abstract: The method is based on the reaction of 2-furaldehyde with aniline - acetic acid - SnCl2 reagent (Stenhouse reaction). The sample solution (30 to 60 µL) is injected into the carrier solution (aqueous 40% ethanol) in the auxiliary channel of the instrument illustrated. The other channel contains the reagent. After reaction, the absorbance is measured at 517 nm. A rectilinear response is obtained in the range 1 to 10 ppm and 5 to 20 ppm, respectively, for 60 and 30 µL of injected sample. By using this method, 70 samples could be analyzed in 1 h; the coefficient of variation was <1%. The method has been applied in the determination of 2-furaldehyde in alcoholic beverages.
