1.Storage of pH Glass Electrodes
Sho-term: store in buer solution with pH=4
Long-term: store in buer solution with pH=7
2.Cleaning of the pH glass electrode
If the glass electrode bulb is contaminated, the electrode response time may be
prolonged. CCIa or soap solution can be used to remove di, and then continue to use after
immersing in distilled water for a day. When the pollution is serious, it can be soaked in 5%
hydrouoric acid solution for 10-20 minutes, rinsed with water immediately, and then
immersed in 0.1mol/L HCI solution for a day before continuing to use.
3.Treatment of glass electrode aging
The aging of the glass electrode is related to the gradual change of the glue layer struc-
ture. Older electrodes are sluggish in response, high in membrane resistance, and low in slope.
Soaking and corroding the outer glue layer with hydrouoric acid solution can generally
improve the peormance of the electrode. If this method can be used to regularly remove the
inner and outer adhesive layers, the life of the electrode will increase.
4. Storage of the reference electrode
The best storage solution for silver-silver chloride electrode is saturated potassium
chloride solution. High-concentration potassium chloride solution can prevent silver chloride
from precipitating at the liquid junction and maintain the liquid junction in working condition.
This method is also applicable to the storage of composite electrodes.
