摘要
用油/水界面电化学方法研究离子选择性电极的响应机理,已取得了一定的进展。考虑到以乙基紫-高氯酸根缔合物为电活性物质的高氯酸根离子选择性电极,具有良好的电极行为,故拟对此体系的界面电荷转移行为进行研究,从理论上探讨该电极系统的电极响应行为。
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.
