15.4.8.3.3. As adsorbents

Try these first

1. 1.

   What is nanotechnology?

   Hint

   Think about what scale represents something very small.

2. 2.

   Give an example of a nanoparticle used as an adsorbent.

   Hint

   Think of common types mentioned in the discussion about environmental remediation.

3. 3.

   What scale does nanotechnology operate on?

   • 1-100 mm
   • 1-100 μm
   • 1-100 nm

   Hint

   Remember the comparison to a hair's diameter.

4. 4.

   True or False: Carbon Nanotubes are used for their poor adsorptive properties.

   • True
   • False

   Hint

   Consider their effectiveness in environmental applications.

5. 5.

   Evaluate the potential risks and benefits of deploying nanoparticles in urban water treatment facilities.

   Hint

   Think about long-term environmental impacts.

6. 6.

   Design a research proposal to study the effectiveness of different types of nanoparticles in soil remediation.

   Hint

   Consider the parameters you would measure.
