当氟电极在浓溶液中进行测量后,要经过较长的时间才能完全恢复到正常的空白电势值,这种滞后现象给实际应用造成了不便。作者在实际工作中注意到,用酸化的水清洗电极可以加速电极功能的恢复。通过以pH为4.5左右的盐酸溶液和纯水作为电极清洗液进行
When the fluorine electrode is measured in the concentrated solution, it takes a long time to fully restore the normal blank potential value, which causes inconvenience to the practical application. The author noticed in actual work that washing the electrode with acidified water can accelerate the recovery of electrode function. It is performed by using a hydrochloric acid solution having a pH of about 4.5 and pure water as an electrode cleaning solution
