How to fit nonlinear Elovich kinetic model in OriginPro
HTML-код
- Опубликовано: 25 авг 2024
- This tutorial is primarily for BS, MS or PhD sturents or early career researchers (ECRs) who are analyzing their experimental data for writing thesis or publishing. This video step by step shows how to fit nonlinear Elovich kinetic model [qt = 1/B ln(A B t +1)] in OriginPro easily! The nonlinear forms of these kinetic models are more appropriate than those of linear ones.

Nice Sir. Your videos are very helpful.
Please share my videos so that other researchers can watch these videos.
@@Aminulchem Of course, Sir. Intra-particle is also required in non-linear form.
Suggestion: The non-linear forms of these kinetic models are more appropriate and better approach than linear forms.
Please do for us non lineair isotherm temkin and DR model
Thank you so much for your comment. Please watch all the isotherm videos and subscribe to my channel: ruclips.net/video/QtpsShedsxE/видео.html
If you have further queries please let me know.
@@Aminulchem yes, I see all your isotherm's videos but i didn't find the DR isotherm ! And show as how to get origin 2021 pro because i work with origin 8 thanks a lot
@@Asma-mv7pc Thanks. Here it is- How to fit linear Dubinin-Radushkevich (D-R) isotherm model in origin ruclips.net/video/5uJi5xBq15U/видео.html
Nonlinear DR model has not yet been published. I may try it in future.

J'ai des résultats et j'arrive pas à tracer les courbes non linéaire par les modèles de Langmuir et Freundlich. Voilà un exemple de mes résultats. SVP explique nous comment les tracées.
Merci beaucoup pour votre commentaire. Vous pouvez facilement ajuster la courbe non linéaire du modèle isotherme de Langmuir et Freundlich en regardant cette vidéo :The video shows you how to fit equilibrium isotherm adsorption data to nonlinear Langmuir and Freundlich model using OriginPro easily.:ruclips.net/video/uVlPeDYY8SA/видео.html
Please keep watching and more videos coming on this related topics.
In every non-linear plot, there is necessary to start with zero ? Excluding zero, the value is changes and did not follows the plot.
To start with zero is not necessary
@@Aminulchem I also started from zero in every plots of isotherm and kinetic.
@@ilmakhan6834 Goodluck to your research endeaver.
Great Job, Sir
Thanks and appreciated. Please watch the other videos and subscribe to the channel
Wow!!
well explained
Thanks and appreciated. Please watch other videos on my RUclips channel and subscribe
Thank you so much, I'm very grateful, you helped me a lot
Glad I could help!
Thank you for explaining.....I have a confusion about the value of alpha and beta for nonlinear model ,will you please tell me how to calculate. And when we plot graph the value of A represent alpha and B (beta) ????
Thank you so much for your comment. For simplicity, I used A and B instead of alpha and beta but you have to write alpha and beta everywhere in the equation. Please check out all other videos and don't forget to subscribe.
How to find qe (experimental) and qe (predicted) value in elovich model. Many publications have shown qe (predicted). I have no clue how to get this value. Pls help
Can you Please refer or mention the link or DOI of the research paper? Actually, I have to cite these equations but i cant find the appropriate research paper especially the non-linear equation. Can you please share the link? willbe grateful for your kind gesture. thank you.
Thanks. You can search google by nonlinear fitting of elovich kinetic model for.... Adsorption. You will get a lot of reference.
if i want to make the Arrhenius plot to calculate activation energy, the ln K is from what value? alpha or beta?
Thanks. There is a video on my channel on how to determine Activation energy. Please watch this and visit all other videos and don't forget to subscribe to this channel.
