Porous monolithic glycidyl methacrylate (GMA) and ethylene glycol
dimethacrylate (EGDMA) copolymer [PGME] and three composite samples with
alumina (PGME/alumina) were synthesized by radical copolymerization in a cast
and functionalized by reaction of diethylene triamine (deta) with epoxy groups in
GMA. All the samples were characterized using FTIR-ATR spectroscopy, SEM,
AFM, solid state NMR, thermogravimetry and mercury porosimetry. Additionally,
amino functionalized PGME/alumina with the highest alumina content
(PGME/alumina50-deta) was loaded with chromium [Cr(VI)] ions. Kinetics of Cr
(VI) sorption was investigated in batch static experiments, at 298 K and pH = 2, for
various initial concentrations (Ci = 0.5, 1.5 and 2.5 mM) and analyzed using three
kinetic models. Cr(VI) sorption by PGME/alumina50-deta obeys the PSO kinetic
model, while IPD model suggests some degree of intraparticle pore diffusion control.
