We usually collect isotherms at different temperatures and fit them all to the same model.
Most of my experience has been with Dual-Site Langmiur, the output providing some thermodynamic parameters.
And also help plug-in the parameters for mixed isotherms (e.g., IAST).
I am still new to RUPTURA - seems to be much more powerful, but with power comes too many options.
Are there examples where the data isotherms collected at different temperatures is fit?
