How to Calculate and Solve for Monolayer Maximum Volume Uptake | BET Adsorption Isotherm | Mineral Processing
Last Updated on December 10, 2021
The image above represents monolayer maximum volume uptake.
To compute for monolayer maximum volume uptake, three essential parameter are needed and these parameters are 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)
Vm = 3[(-8)(1 + (4)9)]/45
Vm = 3[(-8)(1 + (36))]/45
Vm = 3[(-8)(37)]/45
Vm = 3[-296]/45
Vm = -888/45
Vm = -19.73
Therefore, the monolayer maximum volume uptake is -19.73 m³.
