Different researchers are testing new sorbent materials using different methods such as the fixed bed column or batch method, and they use several models to support their results, like Langmuir, Yoon–Nelson, (BDST), Thomas, Elovich equation, the pseudo-first-order equation, the pseudo-second-order equation, and others. So which one is suitable and more important to support and examine the results when testing a new sorbent material?

The models are either kinetic models (pseudo-first-order equation, the pseudo-second-order) or isotherm model (Langmuir, Freundlich etc) and simply you have to check your experimental data with these different models to know which can be applied.
Thank you, Dr. Hany Fathy Heiba
But could you tell me which is more important in terms of applying, serving, and strengthening research?
When testing new sorbent material, you can use for kinetic modelling : the pseudo second order and intraparticle diffusion. For equilibrium modeling use freundlich, Dubinin raduskevich and sips. For both calculation use the non linear equation for the model.
