“…pH 7.4 was selected since it has been reported to be the optimum pH value for hydrogen peroxide detection via electrochemical methods using multiwalled carbon nanotube modified glassy carbon electrodes. 31 This pH offers the potential application for the MnO2-CP-E composite electrodes in biosensors operating in biological media/conditions. No peak is observed in the pH 7.4 phosphate buffer in the absence of hydrogen peroxide.…”

“…Figure 2A compares the voltammetric response of the composite electrode in blank and 1 mM hydrogen peroxide solution in the potential range 0 to þ 1.0 V (vs. SCE) at a scan rate of 50 mV s À1 . The measurements were run in pH 7.4 phosphate buffer since it has been reported to be the optimum pH value for hydrogen peroxide detection via electrochemical methods using multiwalled carbon nanotube modified glassy carbon electrodes [30]. Moreover, this pH offers the potential application for the MnO 2 -CP epoxy composite electrodes in biosensors operating in biological media.…”

Manganese dioxide modified carbon powder was prepared via a wet impregnation method from the solution of permanganate salt. After heating at 120 8C over night in air, the formation of manganese oxide was confirmed by cathodic stripping voltammetry. The synthesized material was used for fabrication of composite electrodes and their potential application in the field of electroanalysis investigated. The composite electrodes based on the manganese dioxide modified carbon powder proved to be useful as electrodes for detection of hydrogen peroxide, ascorbic acid and nitrite ions.

“…First, the electrochemical characterization of the carbon powder epoxy composite (CP-epoxy) and iron(III) oxide modified carbon powder epoxy composite (Fe 2 O 3 /CP) electrodes was performed in pH 7.4 phosphate buffer; pH 7.4 was selected since it has been reported to be the optimum pH value for hydrogen peroxide detection via electrochemical methods using multiwalled carbon nanotube modified glassy carbon electrode. [21] This pH offers the potential application of the Fe 2 O 3 /CP epoxy composite electrodes as biosensors in biological media/conditions. Figure 1 depicts cyclic voltammograms of the carbon powder epoxy (1 : 2 w/w ratio) composite electrode of 6 mm length in a 1 mM solution of ferrocyanide in 0.1 M KCl recorded at a scan rate of 25 mV s À1 .…”

Composite electrodes based on iron(III) oxide, Fe 2 O 3 , carbon powder and epoxy resin have been prepared and characterized using electrochemical methods and X-ray photoelectron spectroscopy (XPS). Initially composite electrodes were made by mixing micron sized carbon powder surface with iron(III) oxide. However, the voltammetric responses were unsatisfactory. Therefore, a new type of composite electrodes was made using carbon powder modified with iron(III) oxide via a wet impregnation procedure. This technique involves saturation of the carbon powder with iron(III) nitrate followed by thermal treatment at ca. 623 K forming iron(III) oxide on the surface of the carbon powder. Several key parameters such as percentage of carbon powder and iron(III) oxide as well as electrode geometry (electrode length) have been optimized. Composite electrodes show attractive performances for the electrochemical detection of hydrogen peroxide and hydrazine with detection limits of 0.12 mM and 1.18 mM respectively. These limits of detection are comparable to the detection limits attained by alternative analytical techniques and are lower than that obtained by other electroanalytical methods.
