Adsorption Isotherm Calculator
Calculate adsorption capacity using Langmuir and Freundlich isotherms for separation process design
About this calculator
The Adsorption Isotherm Calculator helps engineers and scientists determine adsorption capacity using two fundamental models: Langmuir and Freundlich isotherms. This tool is essential for designing separation processes in water treatment, air purification, and chemical manufacturing. By calculating how much adsorbate can be retained by an adsorbent at equilibrium, users can optimize process conditions, select appropriate materials, and predict system performance for efficient separation and purification operations.
How to use
Enter your experimental data including equilibrium concentration, temperature, and known isotherm parameters for your system. Select either Langmuir or Freundlich model based on your adsorbent characteristics. The calculator will compute the adsorption capacity and provide fitted parameters to help optimize your separation process design.
Frequently asked questions
What's the difference between Langmuir and Freundlich isotherms?
Langmuir assumes monolayer adsorption with finite capacity, while Freundlich describes multilayer adsorption with empirical relationships for heterogeneous surfaces.
Which isotherm model should I choose for my system?
Use Langmuir for homogeneous surfaces with defined maximum capacity, and Freundlich for heterogeneous surfaces with varied adsorption energies.
What parameters do I need to use this calculator?
You need equilibrium concentration data, temperature, and either known isotherm constants or experimental adsorption capacity measurements for fitting.
