The image above represents monolayer maximum volume uptake. To calculate monolayer maximum volume uptake, three essential parameters are needed: Volume Measured of Gas Adsorbed (V), c and Gas to Vapour Pressure Ratio (x).
The formula for calculating monolayer maximum volume uptake:
Vm = V[(1 – x) (1 + (c – 1)x)]/cx
Where:
Vm = Monolayer Maximum Volume Uptake | BET Adsorption Isotherm
V = Volume Measured of Gas Adsorbed
x = Gas to Vapour Pressure Ratio
Let’s solve an example;
Find the monolayer maximum volume uptake when the volume measured of gas adsorbed is 3, c is 5 and the gas to vapour pressure ratio is 9.
This implies that;
V = Volume Measured of Gas Adsorbed = 3
c = 5
x = Gas to Vapour Pressure Ratio = 9
Vm = V[(1 – x) (1 + (c – 1)x)]/cx
Vm = 3[(1 – 9)(1 + (5 – 1)9)]/(5)(9)
That is, Vm = 3[(-8)(1 + (4)9)]/45
Vm = 3[(-8)(1 + (36))]/45
Vm = 3[(-8)(37)]/45
So, Vm = 3[-296]/45
Vm = -888/45
Vm = -19.73
Therefore, the monolayer maximum volume uptake is -19.73 m³.
