摘　　要：运用溶胶-凝胶技术将血红蛋白(Hb)固载于玻碳电极(GC)表面,制得Hb/Sol-Gel/GC修饰电极,找出了制备Hb/Sol-Gel/GC修饰电极的最佳实验条件,建立了一种测定过氧化氢的新的、灵敏的方法.同时对该电极与过氧化氢的作用机理进行了探讨.Hemoglobin （Hb） was modified on the surface of glassy carbon （GC） electrode by sol-gel technology to generate a steady Hb/Sol-Gel/GC electrode.The optimal condition for preparing Hb/Sol-Gel/GC electrode was investigated,and a new sensitive analysis method for determination of H2O2 is established based on the modified GC electrode.At the same time,the response mechanism between Hb/Sol-Gel/GC and H2O2 is discussed.
