This question is related to the adsorption of a metalloid ion from the aqueous solution onto an adsorbent, and I wish to have answers on this question in lights of Dubinin isotherms (D-A and D-R isotherms).

Yes, it is possible.
In one of my research work, the amount of qm ( D-R isotherm) is about 5.4 g / g.
In the following article, the qm ( D-R isotherm) is 5.68 g/g (1.42*10-2 mol/g; Molecular Weight of acid red88 = 400.38 g/mol):
