[Voltammetric behaviors of diethylstilbestrol and its determination at multi-wall carbon nanotubes modified glassy carbon electrode].

AIM
To fabricate multi-wall carbon nanotube (MWNT) modified electrode and study the electrochemical behaviors of diethylstilbestrol at the MWNT-modified electrode.


METHODS
Cyclic voltammetry and linear sweep voltammetry.


RESULTS
The oxidation peak current of diethylstilbestrol increased remarkably and the peak potential shifted negatively at the MWNT-dihexadecyl hydrogen phosphate (DHP) modified glassy carbon electrode (GCE), in contrast to that at the bare GC electrode and DHP-modified GC electrode. The oxidation peak current is linear with the concentration of diethylstilbestrol over the range from 1 x 10(-8) to 2 x 10(-6) mol.L-1. The detection limit was 2.5 x 10(-9) mol.L-1. The relative standard deviation (n = 10) was 2.9% for 1 x 10(-6) mol.L-1 diethylstilbestrol.


CONCLUSION
The MWNT-DHP modified GCE exhibits catalytic activity to the oxidation of diethylstilbestrol.
