An electrochemiluminescent detector based on multi-wall-carbon-nanotube/Nafion/Ru(bpy)3(2+) composite film modified heated-electrode.
A new electrochemiluminescent detection system containing a modified and electrically controlled heating carbon paste electrode was developed. Ru(bpy)3(2+) was immobilized in multi-wall carbon nanotube/Nafion composite film, the film was then coated on the surface of carbon paste electrode and the temperature of the electrode could be controlled electrically. The tripropylamine was used to evaluate this ECL detection system with heating electrode. The higher sensitivity, wider linear range and lower relative standard deviation were obtained compared with the unheated modified electrode.
