People Also Ask about
How do you derive the Langmuir isotherm?
We may derive the Langmuir isotherm by treating the adsorption process as we would any other equilibrium process - except in this case the equilibrium is between the gas phase molecules, together with vacant surface sites, and the species adsorbed on the surface.
What is the derivation of Langmuir adsorption isotherm?
The Langmuir Isotherm is derived by treating the adsorption process as any other equilibrium process. However, the exceptional fact about this case is that the equilibrium happens between the gas phase molecules and the species adsorbed on the surface that also includes the vacant surface sites.
What is the reference of the Langmuir isotherm?
Quick Reference The Langmuir adsorption isotherm can be written:θ=bp/(1+bp), where θ is the fraction of the surface covered by the adsorbate, p is the pressure of the gas, and b is a constant called the adsorption coefficient, which is the equilibrium constant for the process of adsorption.
What is the Langmuir model of adsorption isotherm?
The Langmuir isotherm model assumes that adsorption is a homogenous process in which adsorbate (dye) is adsorbed in the form of a monolayer (the thickness of the layer is of the order of one molecule) onto adsorbent (HCP) with adsorption taking place at fixed number of adsorption sites with no lateral interaction or
What is the equation for the adsorption isotherm?
The adsorption equation of the isotherm is represented as: x/m = Kp1/n where x is the adsorbate mass, m is the adsorbent mass, n and K are constants for an adsorbent and adsorbate at a temperature and 1/n is essentially the value at high pressure which is 0 with p being pressure.
What is the equation for the Langmuir plot?
The last linear regression commonly used is the Langmuir linear regression proposed by Langmuir himself in 1918: A plot of (c/Γ) versus (c) yields a slope = 1/Γmax and an intercept = 1/(KΓmax).
What is the principle of Langmuir adsorption isotherm?
The Langmuir adsorption isotherm is used to describe the equilibrium between adsorbate and adsorbent system, where the adsorbate adsorption is limited to one molecular layer at or before a relative pressure of unity is reached.
What is the interpretation of Langmuir adsorption isotherm?
The Langmuir isotherm model assumes that adsorption is a homogenous process in which adsorbate (dye) is adsorbed in the form of a monolayer (the thickness of the layer is of the order of one molecule) onto adsorbent (HCP) with adsorption taking place at fixed number of adsorption sites with no lateral interaction or
