2. Sampling/Adsorption and Extraction/Desorption

Try these first

1. 1.

   What is adsorption?

   Hint

   Think about how substances stick to surfaces.

2. 2.

   Name one method of collecting samples.

   Hint

   Consider types of bags or containers.

3. 3.

   What process is used to separate analytes from an adsorbent?

   • Adsorption
   • Desorption
   • Filtration

   Hint

   It involves getting analytes out of the adsorbent.

4. 4.

   True or False: Breakthrough occurs when the concentration of analytes in the effluent is lower than in the influent.

   • True
   • False

   Hint

   Think about what saturation means.

5. 5.

   Given a breakthrough curve, identify the point of saturation and explain its significance.

   Hint

   Look for the intersection point in the curve.

6. 6.

   In a sampling system with two adsorbent types, predict how the choice of adsorbent affects the results depending on the target analyte.

   Hint

   Consider what makes certain adsorbents better for specific compounds.
