| 摘 要： | 选用氟离子选择电极为测试对象，饱和甘汞电极为参比，测定加入不同类型表面活性剂对氟离子选择电极检测下限的影响。发现阳离子表面活性剂ＣＰＢ对氟离子选择电极有较明显的增敏作用。使电极的检测下限降低，响应时间缩短，稳定性变好。

| Abstract: | The fluoride ion selective electrode was used as tested object ,and the saturated calomel electrode as tested reference so as to test the influence of fluoride ion selective electrode to the lower limit of detection by adding different types of surfactant.The results show that cationic surfactant CPB has an sensitization to the fluoride ion selective electrode,and can decrease the lower limit of detection of electrode,shorten the response time and make the stability better. |

| Keywords: | surfactant lower limit of detection sensitization |
