Hydrogen Peroxide Orp Measurement
Method of measuring the redox potential of peroxide
If you want to measure the redox potential (ORP) of hydrogen peroxide, you must have a method. Prepare all kinds of equipment, clean electrodes, and suitable instruments first, and calibrate accurately to ensure the accuracy of the data.
During operation, place the electrode lightly in the test solution containing hydrogen peroxide, and the action should be slow, so as not to disturb the state of the test solution. Wait until the number is stable before recording its value. During this process, the temperature and humidity of the environment, the concentration of the test solution, and impurities can all affect the measurement result.
The temperature and humidity should be controlled in a suitable area. If the temperature is too high, the reaction will accelerate, and the ORP value may fluctuate abnormally. If the humidity is too high, the electrode may be rusted, causing the measurement to be inaccurate. The concentration of the test solution is also the key. If it is dilute, the signal is weak, and it is difficult to obtain an accurate number. If it is thick, it may cause the electrode to polarize, causing the result to be biased. The presence of impurities, or the reaction with hydrogen peroxide, or the change of its redox balance, so the test solution should be pure.
When measuring, also pay attention to the maintenance of the electrode. After use, clean it with pure water, and store it properly to prevent it from being damaged. In this way, the accurate value of the redox potential of hydrogen peroxide can be obtained
