摘要
采用恒电流聚合制得聚吡咯(PPy)膜修饰电极传感器,该电极传感器对氟离子(F-)具有一定的电流响应性能。进一步实验表明聚吡咯修饰电极传感器可用于快速检测茶叶中的氟离子。
The modified electrodes with a fluorion -doped polypyrrole were prepared by the constant current method on carbon fiber base. It showed that the linear response of F-was 10-1M to 10-5.5M and the modified elec- trodes can be used to determine the content of fluorine ionic in tea.
