So useful. I am a microbiology student trying to come to grips with various bio processing. Deeply appreciate the short references to uses as you explain mechanisms. Glad to have stumbled upon your channel- also thanks for going old school with drawing, still think it superior to slides.
Thanks, I'm glad you like it. And I agree 100%: for topics with a lot of math derivations, writing on a chalkboard has a lot of advantages over PowerPoint.
4:16 thanks sir you cleared my doubt I was wondering that mobile phase was not sticking to the surface of stationary phase so how the adsorption was occuring Now I understood that adsorption was taking place between molecules of mobile phase and stationary
Prof. Stuart: Almost all the videos you have posted pertain to adsorption from gas phase. Are there any lectures on liquid phase adsorption when the adsorbate is in a liquid phase and is being adsorbed onto a solid substrate? I thank you very much for your feedback.
For understanding these models (which is the point of these videos) it really doesn't matter too much whether the application is gas- or solution-phase adsorption. But you're right, I tend to talk as if it is adsorption from the gas phase. For models that are specific to adsorption from solution, you'll probably need to look for chemical engineering sources (not physical chemistry).
Prof. Stuart - could you please give me an idea of the sequence of the recordings for all videos you have on Adsorption? I think the manner in which I am going through them, they are out of sequence. If you can tell me which one to watch first (I am assuming this should have been my very first video to watch) and then the sequence, I would appreciate it very much. Thank you for your help.
Not silly at all... it's a very common question. I'm writing normally (with my right hand), but the image gets reversed digitally. More details: th-cam.com/video/YmvJVkyJbLc/w-d-xo.html
@@PhysicalChemistry - Thank you for the explanation video. I'm a senior biochemist and I could not turn off my curiosity about the "backwards" writing. Now I just have to learn to accept that I am looking at a mirror image of you. The dilemma of digital.
I am working in lime plant And i need to try a trial thus i put activated carbon inside smokestack to adsorp CO,CO2 emissions resulted from natural gas So I need to know 1- the amount of Activated carbon need to add and the factors which affect on AC qty? 2- what happened to CO2 emissions emissions after adsorption on surface of AC ; will be condensed or how to remove it later? 3-how much time of compeltly adsorption reaction between AC and emissions ? 4- Can dust affect on efficiency of adsorption and AC and what will happen during connection between them? 5- when can I change AC during using in adsorption process?
So nobody is gonna talk about how he was writing backwards the whole time 😮
I wasn't writing backwards... I just asked the computer to film backwards: th-cam.com/video/YmvJVkyJbLc/w-d-xo.html

your explanation of the thermodynamics of adsorption was fantastic
Thanks, that means a lot
Very helpful video, thanks for sharing
You are good man this is what I've been waiting for
I'm glad you found it
Appreciate the work really had me stuck there
Great, I'm glad I could help
Very informative. Thank You
You're welcome; glad you found it useful
Very usefull video. Thanks 👏
You're welcome, thanks for the comment

Yes, it's a dynamic equilibrium. Binding and dissociating
You mah boi, you know it
great and awesome
Great!
Thanks

@@PhysicalChemistry Thank you, Prof. Stuart.
I don't get why the substrate is called absorbent, and not adsorbent, that part is confusing to me. The rest was pretty clear, easy to understand.

Yes, this is the first one. The playlist, with the intended sequence, is here: th-cam.com/video/q8Eu5Gntsuc/w-d-xo.html
@@PhysicalChemistry Prof. Stuart - Thank you very much for your reply. I appreciate it very much.
Nice presentation! Silly question: Are you writing on the glass "backwards?"

I love you sir
That's too kind, but my goal is to make you love PChem!
I am working in lime plant
And i need to try a trial thus i put activated carbon inside smokestack to adsorp CO,CO2 emissions resulted from natural gas
So I need to know
1- the amount of Activated carbon need to add and the factors which affect on AC qty?
2- what happened to CO2 emissions emissions after adsorption on surface of AC ; will be condensed or how to remove it later?
3-how much time of compeltly adsorption reaction between AC and emissions ?
4- Can dust affect on efficiency of adsorption and AC and what will happen during connection between them?
5- when can I change AC during using in adsorption process?
You're certainly not the only one. CO₂ scrubbers are very common in chemical engineering. Best of luck with your project
But i just have activated charcoal but I don't know what is the suitable amount added ?
And the reaction time between AC and natural gas emissions
