Langmuir Adsorption Isotherm Formula
Langmuir adsorption Isotherm explain relationship between the number of active site of the surface undergoing adsorption and pressure.
Equation:
Where ,
a and b = constant
x = mass of gas adsorbed
m = mass of the adsorbent
P = pressure
- At low pressure:
x/m = aP
- At High pressure:
x/m = a/b
- AT intermediate pressure
x/m = aPn
