0.01 g of mesoporous powder was mixing with 10 mL
of acid orange 7 solution at
various concentrations
–
In the better conditions,
101 mg/g of dye would be
adsorbed on the materials

Adsorption kinetics: 0.20 g
of adsorbent was mixing at
200 rpm with a CR aqueous
solution of 20 mg/L
–
Equilibrium time is obtained
after 10 min of reaction.
