What Techniques are Used to Control pH in Catalytic Systems?
Several techniques are employed to maintain and control the pH in catalytic systems:
- Buffer Solutions: These are used to resist changes in pH upon the addition of small amounts of acids or bases. - pH Stat Method: This involves the continuous addition of acid or base to maintain a constant pH. - Electrochemical Methods: pH can be controlled using electrochemical cells where the pH is adjusted by electrolysis. - Continuous Monitoring: Using pH meters and sensors to continuously monitor and adjust the pH in real-time.
