"Amperometric Detection Of Simple Alcohols In Aqueous Solutions By Application Of A Triple-pulse Potential Waveform At Platinum Electrodes"
Anal. Chim. Acta 1981 Volume 132, Issue 1 Pages 1-10
Scott Hughes, P. Lawrence Meschi and Dennis C. Johnson

Abstract: Application of a triple-pulse waveform is described for the anodic detection of methanol, ethanol, and ethylene glycol. The execution of the waveform incorporates the cleaning and reactivation of the platinum electrode, by alternate anodic and cathodic polarization, with measurement of the faradaic signal for the analyte at the reduced electrode surface. Some results for formic acid are also presented. The waveform is completed within approximately 2 s and the faradaic signal exhibits no decay with time as would be the case for amperometric detection at a constant applied potential. Calibration curves made by plotting -1/I vs. 1/C are linear. This is consistent with a reaction mechanism in which the analyte is adsorbed prior to anodic detection. The technique is applicable for detection in chromatographic and flow-injection systems.

"Anodic Amperometry And Kinetics Of 2 To 4-carbon Glycols At The Nickel Electrode"
Anal. Chim. Acta 1988 Volume 208, Issue 1-2 Pages 247-254
Nader Botros and Calvin O. Huber

Abstract: Anodic amperometry of nine C3 and C4 alcohols and diols, plus ethanediol and glycerol, was studied at +0.55 V (vs. the SCE) in 0.1 M NaOH containing suspended Ni(OH)2 (from adding 10 mM NiSO4). The flow injection cell contained a 10-mm Ni-wire (0.64 mm diameter) working electrode and a 20-mm Pt-wire auxiliary electrode. The upper limit of rectilinearity (peak current vs. concentration.) was ~0.25 mM and the lower detection limit was 0.2 µM (propane-1,3-diol). Primary alcohols yielded larger current sensitivities than secondary alcohols.

"Periodate Determination By FIA With Chemiluminescence Emission Detection And Its Application To Ethylene Glycol [ethanediol]"
Talanta 1989 Volume 36, Issue 3 Pages 357-362

Abstract: The method is based on measurement of the chemiluminescence generated by the oxidation of pyrogallol (I) by IO4-. A 40 µL sample is injected into a carrier stream of phosphate buffer solution of pH 8.0, which is then mixed with a reagent stream of 1 mM I - 1 mM hydroxylamine. The detection limit is 0.35 µg of IO4-, and the coefficient of variation is 3%. The method can be applied in the determination of ethanediol (II). II is treated with an excess of IO4- in buffer solution of pH 8.0, and residual IO4- is determined as before. The detection limit of II is 0.5 µmol. The sampling rate is 15 min-1.
