In my removal work, the surface area of the adsorbent is only 45 m2/g, but its adsorption capacity is 1297 mg/g!
Why is this happening? Please give me suitable references about the theory that supports your argument.
Hello dear researcher,
What kind of adsorbent did you use? And what was the adsorbate?
Hello,
you could try to see what is the surface of the molecule/ion of adsorbate and transform the mg of this adsorbate in surface and see how far or near you are.

Many thanks for your response.
my adsorbent is Zn/Ce-Layered Double Hydroxide. and the adsorbate is oxytetracycline.

Thanks a lot for your response.
How I can do this transformation?
Not only the surface are can influence the adsorption capacity, also surface chemistry has a great effect on adsorption uptake, hydrogen bonds, electrostatic attractions, in addition to pore filling. This high adsorption capacity is maybe due to the high affinity between the adsorbate and adsorbent, as well as the pH of the solution.
Could you please provide me with your pHpzc and pH of your solution? To get a good picture

Could you give me some suitable references for your explanation?
The pHpzc = 6.9 and the optimum removal pH solution = 6.0
