Tantawy, what types of adsorbate do you want to use again. which dye adsorbed, and what was the adsorbent? Did you worked at ambient temperature?

I think you mean to say  adsorbent(adsorptive surface) not adsorbate(dye)

I have not read your response

yes i need to use this surface again 

After desorption you can reuse that adsorbent

I thought u are taking about adsorbent . In case of adsorbate u can use new sorbate

Of same material for further sorption

You can't reuse sorbent because it fully saturated with dye molecules. Adsorbent may partially recovers its activity on activation .
