About this Engineering article
Electrocatalytic Response of Norepinephrine at a β-Cyclodextrin Incorporated Carbon Nanotube Modified Electrode by Geyun Wang; Xiujuan Liu; Bo Yu; Guoan Luo is a Engineering article available to read on EtoBox.
In 0.1 M KH 2 PO 4 + Na 2 HPO 4 buffer solution (pH 6.0), the b-cyclodextrin incorporated carbon nanotube modified electrode (b-CD/CNT/ME) exhibits a strong catalytic effect toward the electro-chemical oxidation of norepinephrine (NE). The peak current increases linearly with the concentration of NE in the range of 1:0 Â 10 À6 -3:0 Â 10 À4 M. The detection limit is 5:0 Â 10 À7 M. Using cyclic voltammetry, we obtained two peaks for ascorbic acid (AA) and NE in the same solution. The separation between the two peaks is about 264 mV.
