• Cefixime
• modified electrode
• electrooxidation
• real sample

In this research, a modified electrode has been produced by mixing of graphite and multiwall carbon nanotube (MWCNT-CPE). This modified electrode has a very good activity toward the cefixime electrooxidation in a phosphate buffer solution (pH=5). Under optimal experimental conditions, the peak current response increased linearly with cefixime concentration over the range of 3-12 x10(3) mu M. The detection limit (36) of the method was 2.5 mu M. Therefore, this modified electrode was a simple, rapid and effective electrode to determine cefixime in pharmaceutical preparations.
