Abstract:
The e lectrochem ica l behav ior of SudanⅡ w ith BH b w as investigated at the CNTs m od ified GC e lectrode using the cyc lic voltamm etry. It w as found SudanⅡ can undergo a quas-i reversib le electrochem ical reac tion at the CNTs/GC e lectrode. The form a l potentia,l E 0′ is 55mV. A t the BH b /CNTs/GC electrode, the e lectrochem ica l reaction o f SudanⅡis a lso quas-i revers ible. H ow ever, E 0′  is 70 mV. It is positive ly sh ifted 15 mV, com par ing w ith tha t a t the CNTs/GC e lectrode. Th is demonstra ted that Sudan? has interacted w ith BH b. The in terac tion between SudanⅡ and BHb is a lso re lated to the pH of the so lu tion. When the pH o f the so lution is 4.5, the ir interaction is the strongest
