I want to plot non-linear isotherm models together for Langmuir, freundlich and temkin. However I tried to do so but encountered some issues. Therefore is there any one who could help me out with it equation and its parameters setting in origin?
You need to creat a user defined function to fit the data and there are tutorials available online.
In my point of view the youtube videos are the best option and you can easily understand
Why not to share your equilibrium data to paritcipants of RG. It is easier then to help. Moreover, all the isotherms you mention are nonlinear functions (hyperbolic, power and logarithmic). Talking about nonlinear isotherms in this case is a misunderstanding. The only linear isotherm is the Henry isotherm.
Greetings,
I find this article very helpful. The SI provides a detailed instructions on how to plot the regression functions.

I think Professor Nibou Djamel suggestion is nice for you to see youtube video first.

Asif shared a really useful link for you please go a head and see the video clearly...good luck
Did you search the Md. Aminul Islam youtube channel? You will find very useful videos.
To all. I will repeat again. All isotherms are nonlinear functions except for the Henry isotherm. And the so-called linearization is actually a non-linear transformation, which additionally changes the statistical distribution of errors.
