In this thesis, two electrochemical activation methods and two activation solution were used to obtain four types of the activated GC electrodes. Effects of electrochemical activation procedure on the structure, the size, the distribution and the type of electron transfer site on electrode surface have been investigated. Application of electrochemical activation GC electrode has been exploited in electroanalysis of metal ions. Meanwhile, the essence structure and character of electron transfer site of sp2 hybridized carbon material have been explored.
