  • $q$ is the amount of gas absorbed,

  • C is the concentration of the gas in the bulk,

  • k is the adsorption equilibrium constant,

  • $q_{m}$ is the maximum adsorption


2. Gibbs Adsorption Equation:

$\frac{{\Delta G_{ads}}}{A} = -RT \ln(\theta)$

  • $\Delta G_{ads}$ is the Gibbs free energy of adsorption,

  • A is the surface area,

  • R is the gas constant,

  • T is the temperature,

  • 0 is the degree of adsorption.


3. Freundlich Adsorption Isotherm:

$\frac{x}{m} = kC^n$

Where:

  • x is the mass of the gas adsorbent,

  • m is the mass of the adsorbent,

  • C is the equilibrium concentration of the gas,

  • k and n are constants.


4. BET (Brunauer, Emmett, and Teller) Isotherm:

$ \frac{{v(v-1)}}{{P(P-v)}} = \frac{1}{{C_1v^{(1-n)}}} - \frac{1}{{C_2v^{(2-n)}}}$

Where: 

  • $v$ is the volume adsorbed,

  • P is the pressure
