Gas Adsorption - (Wikipedia)

In this experiment you will learn about gas adsorption to a solid surface.

Objectives

In this experiment you will study the phenomenon of gas adsorption to a solid material. You will learn about:

  1. The principles of physical and chemical adsorption.
  2. Langmuir and BET models of adsorption.
  3. Adsorption kinetics of N2 gas on active charcoal.

You will use the Langmuir and BET isotherms to calculate the adsorption coverage surface of active charcoal.
