What techniques can determine the number of active sites?
The adsorbent I use is clay for dye removal
Vanderson Silva, Why do you need the number of active sites per unit of adsorbent surface? The specific surface area is important, and most of all the mass of the adsorbed dye, which you determine on the basis of changes in the concentration of the dye solution. And if you know the mass and surface area and additionally put on one molecule, one active site, no further hints are needed.
To determine the number of active site. You need first the surface area using BET method. You should know also the type of pore on your clay material by determining the iodine number and methylene blue index.
One-touch-button device can of course be used here, but this is a large cost.But, it is important to effectively remove contaminants, not to count active sites. It is enough if we can determine the value of qmax.
