摘　　要：将杯[6]芳烃衍生物修饰到玻碳电极表面制成化学修饰电极，研究了在酸性介质中的伏安特性，并探讨了伏安性能对金属离子的识别．结果表明：修饰电极在0．1mol·L^-1的HAe溶液中对镉离子有很灵敏的伏安响应．线性范围为7．0×10^-9-3．0×10^-7mol·L^-1，检出限为2．7×10^10mol·L^-1．Novel glassy carbon electrode modified by Calix [ 6 ] Arene was firstly prepared. Voltammetrie characteristic of the modified electrode and application in recognition of Cd^2＋ were investigated in acid solution. The results show that the modified electrode has a sensitive response to Cd^2＋ ions in 0.1 mol· L^-1 HAc solution. The peak currents are linear with the concentration in the range from 7.0 × 10^-9 -3.0×10^-7mol·L^-1 .The detect limit is 2.7 × 10^-10 mol·L^- 1.
