How do you Linearize the Langmuir equation?
Langmuir, Freundlich isotherm and Redlich-Peterson equation) were studied….Table 1.
| Isotherm | Non-Linear equation | Linear equation |
|---|---|---|
| Langmuir-1 | C e q e = C e q m + 1 bq e | |
| Langmuir-2 | q e = q m bC e 1 + bC e | 1 q e = 1 bq m 1 C e + 1 q m |
| Langmuir-3 | q e = q m ā 1 b q e C e | |
| Langmuir-4 | q e C e = bq m ā bq e |
What is the equation form of Langmuir adsorption isotherm?
Solution : According to Langmuir isotherm, `x/m=(aP)/(1+bP). `
What is Langmuir constant?
The Langmuir constant (K) indicates the extent of interaction between adsorbate and the surface. If the value of K is relatively larger it indicates that there is a strong interaction between adsorbate and adsorbent while smaller value implies a weak interaction.
What are the inherent assumptions in the Langmuir model of adsorption?
The fundamental assumptions inherent to the SSL model are: i every binding site is identical, ii there are no interactions between adsorbed molecules, and iii there are no interactions in the gas phase i.e., it is an ideal gas .
What is the Langmuir adsorption constant?
What is B in Langmuir isotherm?
Q0 is the monolayer adsorption capacity (mg gā 1) b is the constant related to the free adsorption energy and the reciprocal of the concentration at which half saturation of the adsorbent is reached.
Which of the statement is true about Langmuir adsorption?
Solution : Langmuir’s adsorption is monomolecular i.e., the gas adsorbed forms unimolecular layer.
What is KL in Langmuir isotherm?
The Langmuir KL constant is a measure of the metal ions affinity to the adsorption sites. Can be approximated with a the equilibrium constant.
What is Langmuir constant B?
The average values of the empirical constant and adsorption constant (saturation coefficient) for the Langmuir equation were a = 0.022 mg/g and b = 1.46 l/mg, respectively.
