Okay, so "absorb" sounds like it's not be the exact right word. I am a layman here. But how long does it take for the outer few layers of glass to achieve a level of PFAS density which is meaningful to people seeking to use those outer layers? Do diffusion calculations offer insight into this?
Yes, that is surface diffusion. When anything lands in the surface that is ‘adsorption’. Then those molecules can either surface diffuse, desorb, or go somewhere else :)
Usually water is adsorbed on everything we interact with.
