Isotherm II

Hi I am interested in knowing about what adsorption isotherm is as well as the details of the type II adsorption isotherm?

[Rajkumar Agarwal]

The procedure of Adsorption is typically examined through charts know as adsorption isotherm. It is the diagram between the measures of adsorbate (x) adsorbed on the surface of adsorbent (m) and weight at consistent temperature. Diverse adsorption isotherms have been Freundlich, Langmuir and BET hypothesis.

Basic Adsorption Isotherm

During the time spent adsorption, adsorbate gets adsorbed on adsorbent.



As indicated by Le-Chatelier standard, the bearing of harmony would move toward that path where the anxiety can be alleviated. If there should be an occurrence of utilization of abundance of weight to the balance framework, the balance will move toward the path where the quantity of atoms diminishes. Since number of atoms diminishes forward way, with the increments in weight, forward heading of harmony will be favored.




Type II Adsorption Isotherm


Sort II Adsorption Isotherm indicates vast deviation from Langmuir model of adsorption.

The halfway level locale in the isotherm relates to monolayer arrangement.

In BET condition, estimation of C must be vast in contrast with 1.




Cases of Type-II adsorption are Nitrogen (N2 (g)) adsorbed at - 1950C on Iron (Fe) impetus and Nitrogen (N2 (g)) adsorbed at - 1950C on silica gel.
