“…Several chemiluminescence reagent systems that are similar to those under examination in this study have been used to detect this compound (17,19,(41)(42)(43).

“…We have previously found that the determination of synephrine in herbal weight-loss products with reagent system 3 (permanganatepolyphosphates) required chromatographic separation of the target analyte from numerous interferents (15). Luminol has been used extensively for chemiluminescence detection after chromatographic or electrophoretic separations, and these reports include luminol-hexacyanoferrate(III) systems for post-column or post-capillary detection of certain phenols (17,30,42). Post-column detection with acidic potassium permanganate (18) or cerium(IV) and rhodamine B (46,47) has been employed far less often, but these two reagent systems show great potential for this function.…”

“…Two of the three chemiluminescence reagent systems (luminol and permanganate) have been used to detect a wide range of other compounds, including many with phenolic functionality (16)(17)(18). The reaction of phenolic compounds with cerium(IV) and rhodamine B has been less extensively explored, but Cui and 91 co-workers have recently shown that numerous phenols respond to a closely related reagent system consisting of cerium(IV) and rhodamine 6G (19).…”

Selectivity and potential interference from phenolic compounds in chemiluminescence methods for the determination of synephrine

Three recently reported chemiluminescence methods (based on reactions with alkaline luminol and hexacyanoferrate(III); acidic cerium(IV) and rhodamine B; and acidic permanganate with polyphosphates) for the determination of synephrine were re-evaluated in terms of their selectivity towards this analyte in comparison to other phenolic compounds. A fourth reagent system, acidic soluble manganese(IV) and formaldehyde, was also examined. Each set of reagents was sensitive towards synephrine (limits of detection were 3 × 10 -9 , 5 × 10 -8 , 1 × 10 -8 and 1 × 10 -8 mol/L, respectively) but also responded with numerous other phenolic compounds, including some that are present in citrus fruit extracts, dietary supplements and/or biological fluids. It is therefore recommended that the determination of synephrine in these matrices should incorporate physical separation of sample components (e.g. chromatography or electrophoresis). In more general terms, this study illustrates that accurate percentage recoveries for an analyte in spiked samples (without validation against another analytical method) are insufficient to confirm the analytical utility of new flow-injection analysis (FIA) procedures.

Au/TiO 2 nanorod composites with different ratios of [TiO 2 ]: [Au] have been prepared by chemically reducing AuCl 4 -on the positively charged TiO 2 nanorods surface and used to modify boron-doped diamond (BDD) electrodes. The electrochemical behaviors of catechol on the bare and different Au/TiO 2 nanorod composites-modified BDD electrodes are studied. The cyclic voltammetric results indicate that these different Au/TiO 2 nanorod composites-modified BDD electrodes can enhance the electrocatalytic activity toward catechol detection, as compared with the bare BDD electrode. Among these different conditions, the Au/TiO 2 -BDD3 electrode (the ratio of [TiO 2 ]:[Au] is 27:1) is the most choice for catechol detection. The electrochemical response dependences of the Au/TiO 2 -BDD3 electrode on pH of solution and the applied potential are studied. The detection limit of catechol is found to be about 1.4 × 10 -6 M in a linear range from 5 × 10 -6 M to 200 × 10 -6 M on the Au/TiO 2 -BDD3 electrode.

Covalent Modification of Glassy Carbon Electrode with Aspartic Acid for Simultaneous Determination of Hydroquinone and Catechol

et al. 2007

Glassy carbon electrode (GCE) is covalently modified with aspartic acid (Asp). The modified electrode is used for the simultaneous electrochemical determination of hydroquinone (HQ) and catechol (CC) and shows an excellent electrocatalytical effect on the oxidation of HQ and CC by cyclic voltammetry (CV) in 0.1 mol/L acetate buffer solution (pH 4.5). In differential pulse voltammetric (DPV) measurements, the modified electrode could separate the oxidation peak potentials of HQ and CC present in binary mixtures by about 101 mV though the bare electrode gave a single broad response. A successful elimination of the fouling effect by the oxidized product of HQ on the response of CC has been achieved at the modified electrode. The determination limit of HQ in the presence of 0.1 mmol/L CC was 9.0 x 10(-7) mol/L and the determination limit of CC in the presence of 0.1 mmol/L HQ was 5.0 x 10(-7) mol/L. The proposed method has been applied to the simultaneous determination of HQ and CC in a water sample with simplicity and high selectivity.
