摘要
介绍了通过将电极膜抛光处理和内参比电极重新电镀氯化银而修复废旧氟离子选择性电极(FISE)的方法。修复后的电极性能与正常电极基本相同,其线性范围和电极斜率分别为1.00×10^(-2)～5.0×10(-6)mol/和58.5mV/pF(24.5℃)。用于水样氟的分析,其结果与正常电极基本一致。
This paper describes a method of repairing the scrapped fluorine ion-selective electrode (F-ISE)by means of polishing the electrode membrane and reelectro-plating AgCl on the internal reference electrode. The functions of repaired F-ISE are just the same as the normal electrode ,its calibration range and electrode slope are 1.OO×10-2~5.0×10-6mol/L and 58. 8mV/pF(24.5℃),respectively. The results of analysing fluoride content in water samples with the repaired and normal F-ISE are fundamentally identical.
