Gas-Solid Systems: Langmuir Isotherm Adsorption in gas-solid systems is relatively simple. Experiments showed that the volume of gas adsorbed on solid increases with pressure rapidly…

Difference between Physical adsorption and Chemisorption Physical adsorption is a process in which the electronic structure of the atom or molecule is barely perturbed upon…

Nature of Adsorption Commonsense suggests that if adsorption results from purely physical forces like van der Waals forces it will have a pattern or nature…

Absorption and Sorption Absorption refers to the accumulation and penetration of the particle through the surface inside the bulk of the absorbent. An example is…

Adsorption on the surface of a material may be defined “as a process in which the concentration of a chemical species is greater on the…

Nature of Surfaces The atoms or molecules on a surface of a liquid or solid are subjected to unbalanced forces due to their positions. A…
