Nanocomposite of poly (glycidyl methacrylate-co-ethylene glycol dimethacrylate) and acid modified bentonite was prepared by radical suspension copolymerization. The porosity of the obtained nanocomposite was confirmed by mercury porosimetry. In order to be tested as sorbent for phenol derivatives the composite was functionalized with diethylene triamine and denoted CP-SA-deta. Sorption at constant temperature (25 °C) was performed on water solutions of three phenol derivatives: 4-nitrophenol (4NP), 2-nitrophenol (2NP) and 2-chloro-4-nitrophenol (2Cl4NP). The influence of pH, sorption time and initial concentration of sorbates on sorption efficiency of CP-SA-deta was studied. The isotherm data were best fitted with Langmuir model, while the sorption dynamics obeyed the pseudo-second-order kinetic model for all derivates. Under the same experimental conditions the sorption capacity of CP-SA-deta toward phenol derivatives increased in the following order qmax(2NP)=0.34 mmol g-1 < qmax(4NP...)=0.58 mmol g-1 < qmax(2Cl4NP)=0.70 mmol g-1. On the other hand the sorption rate was similar for 2NP and 4NP, but somewhat slower for 2Cl4NP. The synthesized functionalized nanocomposite can be regarded as promising sorbent for phenol derivatives.
