Crosslinked macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) and
copolymer nanocomposite with acid modified bentonite clay were prepared by radical suspension
copolymerization and functionalized with diethylene triamine. Both samples were characterized by
elemental and textural analysis (mercury intrusion porosimetry). The incorporation of the acid
modified clay into the copolymer matrix lead to the increase of porosity, total pore volume and
particularly specific surface area, while the process only slightly altered the acid–base properties.
The obtained amino-functionalized nanocomposite was tested as 4-nitrophenol (4-NP) sorbent. The
influence of pH, sorption time and initial 4-nitrophenol (4-NP) concentration on sorption efficiency
of synthesized samples was studied. Since the pHPZC of the functionalized copolymer and the
functionalized composite was the same, and the amount of amino groups was slightly higher for the
copolymer, the enhanced sorpt...ion properties can be ascribed to improved textural properties of
composite, particularly the increased specific surface area. The isotherm data were best fitted with
Langmuir model, while the sorption dynamics obeyed the pseudo-second-order kinetic model. The
results in this study show great potential for designing functionalized macroporous glycidyl
methacrylate copolymers and their acid modified bentonite composites as promising sorbents in 4-
nitrophenol removal from wastewaters.
