Langmuir Isotherm Calculator Calculate the amount adsorbed on a surface at a given concentration using the Langmuir adsorption isotherm. — free online calculator.

Formula

qe = (Qmax × KL × Ce) / (1 + KL × Ce); RL = 1 / (1 + KL × C₀)
  • Langmuir Isotherm Calculator calculates its result from Ce, Qmax, Kl, C0. It uses the formula qe = (Qmax × KL × Ce) / (1 + KL × Ce); RL = 1 / (1 + KL × C₀). Change any input to recalculate the result instantly.
  • The main inputs are Ce, Qmax, Kl, C0. Enter them in the units and format shown in the calculator.
  • Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Langmuir Isotherm

Inputs
  • Ce: 2
  • Qmax: 3
  • Kl: 4
  • C0: 5

Using Ce = 2, Qmax = 3, Kl = 4, C0 = 5, the calculated result is 0.0476190476.
