Acid concentration meter selection

In this case, it is recommended that you use an ion-selective electrode (ISE) to measure acid concentration. An ion-selective electrode is a sensor used to measure the concentration of specific ions in a solution; it can distinguish between different ions, such as hydrogen ions (used to measure acidity) and iron ions. A hydrogen ion selective electrode (pH electrode) can be used to measure the acidity of a solution; its principle is to calculate the pH value by measuring the activity of hydrogen ions in the solution. In this case, a pH meter can help you measure the acidity of hydrochloric acid formed by the falling-film absorption of hydrogen chloride, without being affected by iron ions in the solution. However, it should be noted that hydrogen ion selective electrodes may not provide highly accurate measurement results in strongly acidic solutions. Overall, it is a suitable choice for measuring the concentration of hydrochloric acid formed by the falling film absorption of hydrogen chloride. When using ion-selective electrodes, make sure to calibrate the device properly and follow the corresponding operating instructions to obtain the best results. If more accurate measurement results are required, you may need to consider using more advanced analysis techniques, such as conductivity measurement or titration. .

It depends on the concentration range of iron ions; if it is at the ppm level, methods such as density, refractometry, conductivity, or ultrasound can all be used effectively. However, if the iron ion concentration reaches hundreds of ppm, the accuracy of conventional analysis methods is severely affected; online titration analysis must be employed, and the iron ion concentration also needs to be appropriately corrected.
