3. Pretreatment method (recommendation)

 prompts: N117 membrane can be pre-treated before use, the specific method is:

First treat 5% hydrogen peroxide at 80°C for 1 hour, then soak in deionized water for half an hour; then cook 5% dilute sulfuric acid (mass ratio) at 80°C for 1 hour; finally soak in deionized water for half an hour, that is Can.

Or according to the user's established habits, only use the electrolyte solution after soaking.
