Here’s a explanation of how aerosols work in surface chemistry:
Aerosols in Surface Chemistry
- Definition: Aerosols are tiny solid or liquid particles dispersed in a gas.
- Surface effect: Because the particles are very small, they have a large surface area relative to their volume.
- Result: The large surface area makes them reactive and able to adsorb substances from the surrounding gas.
Applications / Examples
- Medical sprays (inhalers):
- Fine droplets deliver drugs efficiently to lungs.
- Air purification:
- Aerosol particles can adsorb pollutants in the air.
- Industrial sprays:
- Paints, perfumes, and pesticides use aerosols for better coverage.
Simple tip:
- Aerosols → tiny particles in gas → large surface area → reactive and adsorb substances easily
