离子选择性电场法是电化学分析中普遍应用的一种方法。1985年,我们采用标准加入法对永清县浅牛—6井F~-浓度进行了实验观测。该井位于牛东断裂北伸、牛驼镇凸起顶峰。井深1274米。为Cl—Na型震旦亚界铁岭—雾迷山组岩溶裂隙水。实验所用主要仪器是:PXD—2型通用离子计、CSB—F—1型氟电极、212型饱和甘汞电极、681型磁力加热搅拌器、WMZL—01型温度控制仪及自制恒温水浴锅等。实验证明,离子选择性电极法做为地震地球化学监测的一种手段,在有条件的地方台和群测点是可以普及的。
Ion selective field method is a commonly used method in electrochemical analysis. In 1985, we used the standard addition method to experimentally observe the F ~ - concentration in Shaoxiu-6 well in Yongqing County. The well is located in the northern extension of NiuDong fault, Niu Tuo town protruding peak. 1274 meters deep. For Cl-Na-type Sinian Asia Tieling - Wumishan karst fissure water. The main instruments used in the experiment are: PXD-2 universal ion meter, CSB-F-1 fluorine electrode, 212 saturated calomel electrode, 681 magnetic heating stirrer, WMZL-01 temperature controller and self-made constant temperature water bath . Experiments show that the ion-selective electrode method as a means of seismic geochemical monitoring stations and groups in the conditional test points can be popularized.
