Resumo
Micropore organosilicas (MOs) were synthesized using methyl-phenyl-polysiloxane as precursor. The MOs were characterized using several analytical and functional techniques. The materials were assigned as micropores materials, with specific surface area up to 642 m2 g-1 and yield up to 72.55%. The adsorbents have hydrophobic surfaces and were used for removal of diclofenac from aqueous solutions. The adsorption kinetic and isothermal data were well described by the general order and Sips models, respectively. Diclofenac exhibited a better affinity than NM and the mechanism of adsorption suggested that hydrophobic groups play a key role in the adsorption process.
