BET (Brunauer, Emmet, and Teller) Isotherm

BET (Brunauer, Emmet, and Teller) Isotherm BET analysis provides precise specific surface area evaluation of materials by nitrogen multilayer adsorption measured as a function of......

Deviations from Langmuir Isotherm

Deviations from Langmuir Isotherm Deviations from Langmuir isotherm are quite common, particularly when the gas pressure is high. This deviation is thought to be due......

Langmuir Isotherm Measurement

Langmuir Isotherm Measurement Many systems covering a wide range of temperature obey the Langmuir isotherm. As a matter of fact, deviation from linearity was ascribed......

Gas-Solid Systems: Langmuir Isotherm

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

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

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 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

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 in Chemistry

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......
