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.
