| 摘 要： | 在玻碳电极上修饰一层表面均匀的聚吡咯膜,然后利用钙钛矿和壳聚糖的复合膜来固定牛血红蛋白(Hb),制备出性能良好的过氧化氢生物传感器.采用循环伏安(CV)和扫描电镜对修饰电极进行了表征.该传感器对H2O2具有好的催化响应,且响应快.在优化的实验条件下,所制备的传感器对H2O2的线性范围为7.0×10-6～1.5×10-3mol/L,检测限为9.0×10-8mol/L.

| Abstract: | A uniform film of polypyrrole was electrochemically polymerized and immobilized on the surface of glassy carbon electrode(GCE),and a layer of La0.7Sr0.3NiO3 and chitosan(CS) composite film was absorbed on the surface of PPY film.Preparation of the enzyme modified electrode,used as biosensor for determination of H2O2,was finally completed by immobilization of the bovine hemoglobin(Hb) on to the surface of La0.7Sr0.3NiO3 /CS/GCE.The modified electrode were characterized with cyclic voltammetry(CV) and scannin... |
