J'ai fait le fit non linéaire, du model cinétique PSO, étape par étape mais malheureusement j'ai rien trouvé et ce message affiché par Origin "fit did not converge -reason unknown" . Help me please.
I think you need more practice. Therefore, watch these videos carefully and several times: th-cam.com/video/NUM11s1X-68/w-d-xo.html Then try to fit while watching the video. Hopefully your problems will go. If not solved, please let me know by comments.
Thanks for your comment. Theoretical qe will be same for all model purpose. Please watch this video: th-cam.com/video/GYCUOcpiUec/w-d-xo.html If you have further problem, please let me know & don't forget to subscribe this channel.
Thanks for your comment. Please keep watching all the videos & subscribe to my channel. The original IPD model equation is in the linear form and can't be converted to nonlinear form. Therefore, I have showd how to fit linear IPD easily in origin: th-cam.com/video/FQZPwjqe610/w-d-xo.html
Sir, I have followed the same method as shown in the video but I'm unable to get the non-linear fit. I could get it for Pseudo first order but not for pseudo-second-order kinetics. Is there any other way to do a non-linear fit? Kindly provide your advice. Thank you again.
Thanks for your comment. Probably you could not write function properly. Please double check it and practice again and agin while watching this video and other videos. You can also try to fit nonlinear model using MS Excel solver. Please check my videos. If you have further query, please let me know.
@@Aminulchem Often, graph ln(Co/Ct) vs. time express Langmuir Hinshelwood: ln(Co/Ct) = -k1*t where, Ct = concentration after time t k1 = LH rate constant LH model: (1/r) = (1/k*Ka*Co)+(1/k) where, r = initial rate (mol L^-1 min^-1) k = reaction rate constant (mol L^-1 min^-1) Ka = adsorption coefficient Co = initial concentration Your tutorial will be much help and offer better understanding in this topic Dr. Thank you so much for considering it.
Thanks for your comment. You are absolutely right. At the beginning of the video, I wrongly wrote it as qt, and actually, it will be qe. However, I wrote it correctly during model fitting. Please watch other videos and don't forget to subscribe to this channel.
Well explained thank you sir. However, the equation shown in the starting seems to be wrong on the right side below the under line, it should be qe but not qt. Please correct me if I'm wrong
Thanks. Yes, you are right. On the first page, it was wrong but I wrote the function in the origin sheet correctly. Please watch all other videos and don't forget to subscribe to this channel.

short and informative. Thank you
Glad it was helpful!
I want to create a new method like you did but I can't find "new" in the category box with originlab pro 8.5
Great

@@malapamei13 Happy to help you. If you need more help, please let me know.
@@Aminulchem I could successfully perform the nonlinear fitting for PSO Kinetics. Thank you again!
@@malapamei13 Great to know that. Please keep watching all other videos and you will learn a lot of things.
Good day Dr, can we possibly have a tutorial on Langmuir-Hinshelwood kinetics too?
Thanks. Good idea. I will try to make such a video. Could you please write the equation here?
@@Aminulchem
Often, graph ln(Co/Ct) vs. time express Langmuir Hinshelwood:
ln(Co/Ct) = -k1*t
where,
Ct = concentration after time t
k1 = LH rate constant
LH model:
(1/r) = (1/k*Ka*Co)+(1/k)
where,
r = initial rate (mol L^-1 min^-1)
k = reaction rate constant (mol L^-1 min^-1)
Ka = adsorption coefficient
Co = initial concentration
Your tutorial will be much help and offer better understanding in this topic Dr. Thank you so much for considering it.
Thanks. You can also post data if you have@@scoupiegoe3713
Sir, please check the second term of the of division if really is qt and not qeq.

Thanks. You are right. It has been mentioned in my previous comment.
Thank you alot for this informative video, may i ask you this origin data sheet for all kinetic and isotherm models. Please
Thanks. You can try to fit your own data by watching videos of this channel. If you have a specific query, then let me know.
Dear Professor, I have some doubt. how to find Akaike Information Criteria......Thank you
Thanks. Please elaborate your querries
ok thank you
equation is wrong for the Pseudo you put qe/qt
Thanks . Please check other videos of this channel
