| Abstract: | Using cyclic voltammetry, we examined the electroresponse of Fe2+/Fe3+ ions at 13X-type zeolite modified glassy carbon electrodes. The electroresponse was affected by the immerse time of the electrodes in Fe2+-containing solution,the potential sweep rate and the solution temperature. The results show that the Fe2+ ions may occupy two kinds of electro- chemically distinct sites,and that there is a migration between the Fe2+ ions at these two sltes. |
