【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HAc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.更多还原

【Abstract】 Novel glassy carbon electrode modified by Calix[6] Arene was firstly prepared.Voltammetric 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~ -7 mol·L~ -1 .The detect limit is 2.7×10~ -10 mol·L~ -1 .更多还原
