The monolayer capacity of the adsorbent is equal to number of moles of adsorption sites present on one gram of sample. The Langmuir and BET isotherms may be used to find th monolayer capacity of the adsorbent. Thus on taking the reciprocal of the monolayer capacity, one can find the molecular weight of the adsorbent.

How do you calculate KL in langmuir isotherm?
To calculate the Langmuir constant (KL) in the Langmuir isotherm model, you typically perform a nonlinear regression analysis on experimental data using the Langmuir equation: (q = \frac{{q_{max} K_L C}}{{1 + K_L C}}), where q is the adsorption capacity at a given concentration C, and (q_{max}) is the maximum adsorption capacity. The Langmuir constant (KL) can be determined by fitting the experimental data to this equation and solving for KL.
What is hill isotherm?
The Langmuir equation (also known as the Langmuir isotherm, Langmuir adsorption equation or Hill-Langmuir equation) relates the coverage or adsorption of molecules on a solid surface to gas pressure or concentration of a medium above the solid surface at a fixed temperature.
What is the difference between the Freundlich BET and Langmuir adsorption isotherms?
There are a few differences, but the main one is that Langmuir can only be used for surfaces which are cover by only one layer of gas and the BET surface area is calculated using the multilayer model.
What did langmuir fisher invent?
Langmuir and Fisher are two separate scientists who made significant contributions in different fields. Irving Langmuir was a chemist and physicist known for his work on surface chemistry and plasma physics, while Ronald Fisher was a statistician known for his contributions to the field of statistics, particularly in experimental design and hypothesis testing. Langmuir developed the Langmuir adsorption isotherm, and Fisher developed the analysis of variance (ANOVA) and the design of experiments.
What is Freundlich adsorption isotherm and Langmuir isotherm?
At a given temperature, the extent of adsorption will increase with the increase of pressure of the gas. The extent of adsorption is measured as x/m, where mi= is the mass of adsorbent and x that of adsorbate. At low pressure, x/m varies linearly with p. As per Freundlich adsorption equation Taking log both sides of the equation, we get, At low pressure, x/m=kP At high pressure, x/m=kPo This is called Freundlich adsorption isotherm at a constant temperature. Freundlich isotherm fails at high pressure and is only for physical adsorption. Langmuir isotherm is represented as x/m=ap/(1+bp) (a and b are constants) At very high pressure,(bp>>1) x/m=a/b At very low pressure,(bp<<1) x/m=ap
What should be result of adsorption acetic acid on charcoal?
The acetic acid molecules will be attracted to the surface of the charcoal due to adsorption, leading to their accumulation on the charcoal's surface. This process can be used to remove acetic acid from a solution through physical adsorption without undergoing a chemical reaction.
