This is awesome. I'm writing a literature review paper on clays and was curious about adsorption isotherms in terms of concentration. Do you have a video with more info? I'll take a look.
great that was really helpful, I got a question though, one of the assumption of Langmuir Isotherm was each site can be occupied by one molecule right? so it doesn't mean number of molecules/site should always be equal to 1?
You can do a linearization of the Langmuir isotherm. For liquid systems qe=(qmáx*kL*Ce)/(1+kL*Ce) and (Ce/qe)=1/(qmáx*kL)+(1/qmáx)*Ce. Ce is the equilibrium concentration of the liquid medium [mg adsorbate/L solution] and qe is the amount of adsorbate per amount of adsorbent [mg adsorbate/g adsorbent], those are your experimental values. You can get qmáx from the slope of the linearized form and kL from the intersection point of the Y axis and the slope

Sir what's the tool used to write on the screen by you in this video
Microsoft OneNote on a tablet PC
Thanks for the videos they help so much in understading the concepts

Awesome video!
What software is used for the isotherm?
thank you
Mathematica
Software used?
Obrigado:)
How to apply Langmuir isotherm to experimental data @
you need to find a software to do the curve fitting for you. like nonlinear regression in POLYMATH.
You can do a linearization of the Langmuir isotherm. For liquid systems qe=(qmáx*kL*Ce)/(1+kL*Ce) and (Ce/qe)=1/(qmáx*kL)+(1/qmáx)*Ce. Ce is the equilibrium concentration of the liquid medium [mg adsorbate/L solution] and qe is the amount of adsorbate per amount of adsorbent [mg adsorbate/g adsorbent], those are your experimental values. You can get qmáx from the slope of the linearized form and kL from the intersection point of the Y axis and the slope
Thanks a lot
great, good videos !
