多联吡啶衍生物化学修饰碳糊电极的制备及其循环伏安行为的研究

The Preparation of TPY Chemical Modified Carbon Paste Electr ode and the Study of Its CV Behavior

利用合成的多联吡啶衍生物 6,6″ 二甲基 4′ 苯基 2 ,2′∶6′ ,2″ 三联吡啶 (TPY)制备了新型的化学修饰碳糊电极 ,并研究了Cu(Ⅱ )、Co(Ⅱ )在该电极上的循环伏安行为。结果表明 ,TPY化学修饰碳糊电极对Cu(Ⅱ )、Co(Ⅱ )有显著的富集作用 ,且电极的稳定性和重现性良好。

A new Chemical Modified Carbon Paste Electrode(CMCPE ) has been prepared by using the carbon paste with 6,6″ dimethyl 4′ pheny1 2 ,2′∶6′,2″ terpyridine(TPY).The CV behaviors of Cu(Ⅱ) and Co(Ⅱ) were studi ed at this modified electrode.The results indicated that the TPY modified electr odes have notable concentration characteristic for Cu(Ⅱ) and Co(Ⅱ).Its stabili ty and repeatability were good.This provided a strong theoretical basis for deve loping the analytical method of Cu(Ⅱ) and CO(Ⅱ) further
