2.1. Adsorption Process

Try these first

1. 1.

   What is adsorption?

   Hint

   Think about how substances stick to surfaces.

2. 2.

   Name one common adsorbent material.

   Hint

   Consider materials used for air filters.

3. 3.

   What is the primary function of adsorption in air sampling?

   • To cool the air
   • To trap harmful vapors
   • To filter solid particles

   Hint

   Think about what we want to analyze in the air sample.

4. 4.

   True or False: Desorption always requires the use of a solvent.

   • True
   • False

   Hint

   Consider methods beyond just solvents.

5. 5.

   You are tasked with designing a sampling system for a city monitoring station. Discuss how you would ensure the sampling efficiency and accuracy.

   Hint

   Consider all factors affecting sampling from the air.

6. 6.

   Calculate the theoretical breakthrough point in an adsorption column for a given flow rate and concentration of analyte.

   Hint

   Think about how long it takes for the adsorbent to reach saturation.
