摘　　要：基于氟离子选择电极对OH-的敏感性,提出了一种用NaOH溶液活化再生旧氟离子选择电极的方法,实验结果表明:NaOH溶液浓度在0.005～0.05mol·L-1,活化时间在30～35min为宜.将活化的电极用于样品分析及加标回收率的测定,结果令人满意.A method of activating and regenerating old fluorine ion selected electrode by means of NaOH solution has been pointed out based on fluorine ion selected electrode. The result of experiment shows ： the cleasity of NaOH solution is 0.005 - 0.05 mol·l^ - 1, activating time within 30-35 min. will be suitable. The analysis of the sample of activating electrod and the determination of recollecting rate is sample of activating electrode and the determination of recollecting rate is satifactory.
