“…Therefore, a highly sensitive and selective analytical method is necessary for the simultaneous determination of the three dihydroxybenzene isomers. Up to now, various methods have been exploited for the determination of the dihydroxybenzenes, such as high performance liquid chromatography (HPLC) [3,4], spectrophotometry [5,6] Electrochemiluminescence [7], synchronous fluorescence [8], gas chromatography/mass spectrometry [9], capillary electrochromatography [10], pH-based-flow injection analysis [11], and electrochemical methods [12][13][14][15][16][17][18][19][20][21][22][23]. Among these methods, electrochemical method is of particular interest due to its high sensitivity, low cost, good selectivity, and rapid detection.…”

“…Among these methods, electrochemical method is of particular interest due to its high sensitivity, low cost, good selectivity, and rapid detection. For most electrochemical methods, more attention is focused on the simultaneous determination of CC and HQ due to their redox peaks are overlapped at ordinary electrode [12][13][14][15][16][17][18][19][20]. However, the simultaneous determination of HQ, CC, and RS by electrochemical methods is few reported.…”

A new composite electrode has been prepared with doping graphene into the paste consisting graphite and ionic liquid, n-octyl-pyridinum hexafluorophosphate (OPFP). This electrode shows an excellent electrochemical activity for the redox of hydroquinone (HQ), catechol (CC), and resorcinol (RS). In comparison with bare paste electrode, the redox peaks of three isomers of dihydroxybenzene can be obviously, simultaneously observed at graphene doping paste electrode. Under the optimized condition, the simultaneous determination of HQ, CC, and RS in their ternary mixture can be carried out with a differential pulse voltammetric technique. The peak currents are linear to the concentration of HQ, CC, and RS in the range form 1 × 10 −5 to 4 × 10 −4 , 1 × 10 −5 to 3 × 10 −4 , and 1 × 10 −6 to 1.7 × 10 −4 mol L −1 , respectively. The limits of detection are 1.8 × 10 −6 mol L −1 for HQ, 7.4 × 10 −7 mol L −1 for CC, and 3.6 × 10 −7 M for RS, respectively.

“…OMCs have been widely used in electrocatalytic applications, largely due to their fast electron transfer, avoiding surface fouling, and excellent electrocatalytic activity. The excellent electrocatalytic properties of electrodes modified with OMCs have been reported for different environment pollutants [2,3] and biological molecules [4 -10]. The electrocatalysis of different redox analytes at OMCs paste electrodes or enzymes-incorporated OMCs paste electrodes have been discussed in details [11].…”

Electrochemical Oxidation and Detection of Morphine at Ordered Mesoporous Carbon Modified Glassy Carbon Electrodes

2009

In this work, three ordered mesoporous carbons (OMCs) with different structural parameters were synthesized by a simple variation of the hydrothermal temperature of the silica templates (SBA-15). X-ray diffraction and nitrogen adsorption-desorption results show these OMCs exhibit an ordered 2D hexagonal mesostructure with tunable pore diameter. OMC-modified glassy carbon electrodes exhibit efficient electrocatalytic reactivity toward oxidation of morphine (MO). The amperometric detection of MO in pH 7.0 phosphate buffered saline at þ 0.39 V versus Ag/AgCl is the lowest potential reported to-date. A linear range from 0.2 to 197.6 mM and a detection limit of 0.03 mM MO were obtained.
