[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.
