Abstract: The electroactive system of ethyl violet-perchlorate for perchlorate electrode was studied by Current scan polarography and chronopotentiometry. The results showed that the transfer process of perchlorate ion across the interface of W/DCE is reversible. The response mechanism of perchlorate electrode was verified as a Nernstian response. The standard potential and standard transfer free energy of perchlorate ion are ΔOWΦ0=-0.12V and ΔGtr0W-O=-11.58kJ·mol.
