Abstract ：
A highly selective and sensitive electrochemical sensor for ascorbic acid (AA) assay has been prepared through Cu(I) catalyzed azide-alkyne cycloaddition reaction (CuAAC). The catalyst, Cu(I) species, is acquired from the reduction of Cu(II) by AA in situ. In the presence of Cu(I) catalyst, the azide modified Au electrode surface is shown to react quantitatively with terminal propargyl-functionalized ferrocene forming 1,2,3-triazoles. The electrochemical response of propargyl-functionalized ferrocene modified Au electrode surface can be monitored using differential pulse voltammetry (DPV) technique. Under optimal conditions, it is found that the current intensity has a linear relationship with the logarithm of AA concentration in the range of 5.0 x 10(-12) to 1.0 x 10(-9) M. Furthermore, the proposed electrochemical sensor shows a good stability (RSD 4.2%), high selectivity and low detection limit for AA detection. In addition, it also demonstrates that the proposed sensor can be applied to detect AA in real urine samples with satisfactory results.

Abstract ：
A high-performance CE with amperometric detection (CE-AD) was employed for the kinetic study of keto-enol tautomerism of p-hydroxyphenylpyruvic acid (pHPP). Several factors (concentration of beta-cyclodextrin (beta-CD), concentration and pH of running buffer, separation voltage and injection time) affecting CE-AD were investigated and separation conditions were optimized. The kinetics of pHPP was performed in water solution and phosphate solution under different pH and temperature, the homologous ketonization rate constants and half-life were obtained. Also, the activation energy was calculated according to the rate constants under different temperature. The experimental results indicated that beta-CD played an important role in the separation, therefore UV spectrometric method was applied for the study of complexation interaction between ketonic pHPP and beta-CD. The results indicated that the stoichiometric ratio of the pHPP-beta-CD complex was 1:1 and formation constant was determined. The obtained kinetic results are in correspondence with those reported by our group with CE-UV.

Abstract ：
A room temperature ionic liquid (IL), 1-butyl-3-methylimidazolium hexafluorophosphate (BMIMPF6) was used as a binder to prepare the electrically heated ionic liquid/carbon paste electrode (IL-HCPE). It has been found that N6-isopentenyl-adenine (2-ip) can enhance the electrochemiluminescent (ECL) intensity of Ru(bpy)(3)(2+). The electrode surface temperature (T-e) has great effect on the ECL intensity of Ru(bpy)(3)(2+)/2-ip system. The ECL intensities has a linear relationship with the concentration of 2-ip in the range of 1.0 x 10(-7)-1.2 x 10(-6) mol/L with a detection limit of 3.6 x 10(-8) mol/L (S/N = 3) when T-e was 58 degrees C, while the linear range was of 5.0 x 10(-7)-1.0 x 10(-6) mol/L with a detection limit of 1.8 x 10(-7) mol/L under 27 degrees C. It was also found that the reproducibility of this ECL system would be better at elevating temperature, the RSD were 7.2% and 1.5% for 8.0 x 10(-7) mol/L of 2-ip at 27 and 58 degrees C, respectively. The possible mechanism of the Ru(bpy)(3)(2+)/2-ip ECL system has been proposed also. (C) 2009 Elsevier B.V. All rights reserved.
