Pure adsorption isotherms of adsorbent A for Nitrogen and Methane gases at 46oC are given below as data points. Discuss the applicability of Langmuir, and Freundlich isotherm models for this set of data. Determine the corresponding isotherm parameters for the two different temperatures given for each of the two components and list them in a table. Plot the original data (as n vs. P) in comparison to the fit for each model to show the applicability. Show the original data as data points, and the model curve fits for these isotherm models as different curves. Discuss the applicability of each isotherm model to these specific systems.
