A1 Method Summary
GB 17323—1998
Appendix A
(Standard Appendix)
Determination of Conductivity
Conductivity is the reciprocal of the resistance measured between two electrodes with a distance of 1 cm and a cross-sectional area of ​​1 cm2, and is directly read by a conductivity meter. A2 Instruments and Reagents
A2.1 Instruments
A2.1.1 Conductivity meter (with matching conductivity electrode). A2.1.2 Constant temperature water bath.
A2.1.3 100mL or 250mL beaker.
A2.2 Reagents
0.0100mol/L potassium chloride standard solution: Take a small amount of potassium chloride (superior purity), dry it in an oven at 110℃ for 2h, accurately weigh 0.7456g after cooling, dissolve it in freshly boiled and cooled double distilled water (conductivity less than 1μS/cm), transfer it to a 1000mL volumetric flask, and dilute to the scale. The conductivity of this solution at 25℃ is 1 411.83μS/cm. The solution is stored in a hard glass bottle with a glass stopper. A3 Analysis Steps
According to the instructions for use of the conductivity meter, select the electrode and measurement conditions, and adjust the conductivity meter. After washing the electrode with the test solution 3 times, insert it into the beaker (A2.1.2) containing the test solution. Select an appropriate range, read the reading on the meter, and you can calculate the conductivity value of the test solution. Notes
1 The electrode leads should not be damp, otherwise the measurement accuracy will be affected. 2 The beaker containing the test solution should be cleaned 3 times with the test solution to avoid ion contamination. A4 Precision and Accuracy
The same laboratory measured a water sample with a conductivity of 1.36uS/cm 10 times, and its relative standard deviation was 1.0%. A5 Determination of electrode constant
Take an electrode with an unknown electrode constant, wash it with potassium chloride standard solution (A2.2) 5 times, insert it into a beaker containing potassium chloride standard solution (A2.2), measure the conductivity at a certain temperature, and calculate the electrode constant of the electrode. Electrode constant = K/S
Where: K--the conductivity of potassium chloride standard solution at a certain temperature, which can be found in Appendix A of GB6682. ....(A1)
S--the conductivity of potassium chloride standard solution measured under the same experimental conditions. Note: Some conductivity meters have the electrode constant of the matching electrode marked when leaving the factory, so the compensation correction of the electrode strip number can be directly performed. If the electrode constant of the electrode is unknown, this method can be used to determine it.
