Langmuir assumptions

Jiggling circles represent particles or molecules

Real adsorption is a layer or layers on the surface. To make them more apparent, adsorbed species in this animation are shown under the surface. Motion slowing down with large numbers of particles is an artifact resulting from computation taking longer.

Do you agree?

  • Increased concentration means higher loading (more sites occupied)
  • Attachment is reversible and random
  • Loading cannot be linear function of concentration
