摘　　要：研究了Cu(Ⅱ)在巯基化壳聚糖(CTS-SH)共价键合修饰的金电极上的循环伏安行为。研究表明,在pH=4.9的磷酸盐体系中,离子的氧化还原过程为一准可逆过程,且Cu(Ⅱ)在0.28V处出现一氧化峰,在0.20V处出现一还原峰。The paper introduces the applications of chitosan in the electrol chemistry .It was applied in Au electrode modified with CTS-SH, a better electric current response would obtained in cyclic voltammetry. The cyclic voltammetry behavior of Cu(Ⅱ) on the surface of chemical covalence bonded Auelectrode modified with CTS-SH has been studied in this paper.As the experiment did,the reducing-oxido courseof Cu(Ⅱ) ion is a quasi-reversible one in 0.039mol/L(pH=4.9)NaH2PO4.The experiment has also been witnessed that the oxido peak of Cu(Ⅱ) is at 0.20V and the reducing peak is at 0.28V.
