Web14 apr. 2024 · Precise estimations of the diffusivities inside the adsorbent particles can be obtained by employing the following formula that describes the relationship between the adsorption capacities at equilibrium and at any time (Sivarajasekar and Baskar, 2024): (7) ln [1 1 − F 2 (t)] = π 2 a 2 D e t (8) F (t) = q t q e where q t and q e represent the uptake … Web14 apr. 2024 · The calculated results of fitting parameters of the adsorption kinetics showed that the maximum adsorption capacity of benzene, toluene, 1,2−dichloropropane and TCP were 5.40, 6.58, 2.87, and 1.10 mg/kg, and the adsorption rate constants (k) of them were 0.86, 0.90, 0.82, and 0.74 h −1, respectively.
Pseudo-Isotherms using a second order kinetic expression constant
WebThe experiments revealed that the adsorption kinetics followed the pseudo-second-order rate equation and that the Langmuir equation could best describe adsorption isotherm data. The nanoparticles were characterized using SEM coupled with EDS, XRD, BET surface area, and UV Spectroscopy.
