How nessesary is working point zero charges for any adesorbent?
I want to know how suitable the surface of the material is good for adsorption. I got SEM and FTIR results and thought those are enough to decide.
Dear Dr Alemu: The point of zero charge is the pH at which the surface of your adsorbent is globally neutral, i.e., contains as much positively charged as negatively charged surface functions. Below this value, the surface is positively charged; beyond this value, it is negatively charged. For more on this have a look at:
