Adsorption of the CLE was found to obey the Langmuir adsorption isotherm and underwent both physisorption and chemisorption process. The kinetic and thermodynamic parameters were calculated and discussed in detail.

There are many empirical adsorption models, but the most common is the Langmuir adsorption isotherm model. This model assumes that Webb11 apr. 2024 · Langmuir isotherm and pseudo-second order kinetics models were superior in the prediction of NRFX which features adsorbate-to-adsorbent electron transfer on monolayer surface. The thermodynamics of NRFX adsorption is heavily dependent on the makeup of the adsorbent, and the selection of the eluent for desorption from the … huber jongejan
