Mainly it will be an interaction with silanol groups. To test if some reaction takes place you should use an HPLC or TLC. If chemisorption will take place you will not elute your compound using a solvent with high elution strenght.

Dear Zuafuani,

Yes, it is possible. Try to perform FTIR and XPS analyses of the adsorbed samples. Then follow up the changes occurred. For help, you may go through my publications.

Thanking you very much.

I think that by using XPS analyses of the adsorbed samples you should observe the changes due to adsorption

Dear Zuafuani,

I very much agree what Mr. Karmakar has said. Adsorption mechanism can be depicted by observing the changes in FTIR and XPS spectra. Additionally, XRD can also provide significant information about the surface occupation of the adsorbates, especially crystalline powder dyes or M(II).

Thank you.
