Unlock the secrets of surface adsorption using our free Langmuir Isotherm Calculator. Easily compute equilibrium adsorption (q), maximum monolayer capacity (Qmax), and the Langmuir constant (K) for various adsorbates. Ideal for chemical engineering, environmental science, and materials research.
Formula:
The Langmuir Isotherm model describes monolayer adsorption on a homogeneous surface with a finite number of identical sites. The formula is:
q = (Qmax * K * C) / (1 + K * C)
- q: Amount of adsorbate adsorbed per unit mass of adsorbent at equilibrium (e.g., mg/g)
- Qmax: Maximum adsorption capacity, representing complete monolayer coverage of the adsorbent surface (e.g., mg/g)
- K: Langmuir constant, related to the affinity of the binding sites for the adsorbate (e.g., L/mg)
- C: Equilibrium concentration of the adsorbate in the solution (e.g., mg/L)
