چکیده
|
The direct electrochemistry of hypercin on a modified carbon paste electrode (cpe) was described. the electrode was modified with zinc oxide (zno) nanorods and n-hexyl-3-methylimidazolium hexafluoro phosphate as a binder. the oxidation peak potential of hypercin at the surface of the ionic liquid / zno nanorods / cpe (ilzncnpe) appeared at 320 mv,which was about 100 mv lower than the oxidation peak potential at the surface of the traditional carbon cpe under a similar condition. the linear response range and detection limit were found to be 2.5×10-6- 2.0×10-4 m and 9.1×10-7 m,respectively. © 2016 by cee (center of excellence in electrochemistry).
