摘要:
采用电沉积法将四氨基钴酞菁(CoTAPc)修饰于石墨电极(GE)的表面得到GE poly CoTAPc修饰电极,用该电极对不同浓度H 2O 2溶液进行循环伏安和计时安培分析。结果表明,H 2O 2在GE poly CoTAPc电极上比在裸GE电极上的起始氧化电位明显负移了0.18 V,峰电流 I p增加了150.5 μA,GE poly CoTAPc电极可用作过氧化氢的响应电极。工作电压为1 V时,计时安培法分析得出 I p与H 2O 2的浓度在19.48~194.8 μM浓度范围内呈线性关系,检测下限为4.72 μM。GE poly CoTAPc修饰电极在H 2O 2溶液中平行20次计时安培分析发现电极的检测下限仅下降了1.1%,表明修饰电极具有优良的稳定性。
