WebNov 26, 2024 · As shown in Table 3, both C e / q e versus C e curve and R 2 values indicate that the Langmuir isotherm model had a better fit than the Freundlich model. From the Langmuir model, the maximum adsorption capacity (q m) of ampicillin was calculated to be 252.819 mg/g for CM1, which was higher than that for CM2 (193.274 mg/g). This could … Inherent within this model, the following assumptions are valid specifically for the simplest case: the adsorption of a single adsorbate onto a series of equivalent sites onto the surface of the solid. 1. The surface containing the adsorbing sites is a perfectly flat plane with no corrugations (assume the surface is homogeneous). However, chemically heterogeneous surfaces can be considered to be homogeneous if the adsorbate is bound to only one type of functional groups on the surface. golden crow patreon https://solcnc.com
