What Methods are Used for pH Monitoring in Catalysis?
Several methods are employed to monitor pH in catalytic processes, including:
Glass Electrode: A traditional method using a glass electrode immersed in the reaction solution. It provides accurate and continuous pH measurements. pH Indicators: Chemical compounds that change color at specific pH values, offering a visual way to estimate pH. Optical Sensors: These sensors use changes in light absorption or fluorescence to monitor pH levels, often employed in microreactors and miniaturized systems. Ion-Sensitive Field-Effect Transistors (ISFETs): These devices provide rapid and robust pH measurements, ideal for real-time monitoring in industrial applications.
