Application of macroporous nanocomposite in microextraction of aromatic amine from water

Abstract

Magnetic macroporous poly(glycidyl methacrylate-co-trimethylolpropane trimethacrylate) nanocomposite was synthesized by suspension copolymerization. The obtained nanocomposite was characterized by Fourier transform infrared spectroscopy (FT-IR), mercury porosimetry and scanning electron microscopy (SEM). Such magnetic nanocomposite was applied as sorbent for a dispersive solid-phase microextraction (DSPME) for aniline preconcentration from water samples. The parameters affecting the microextraction were optimized. The screening of DSPME parameters was determined using Plackett-Burman design (PBD). For the optimization of the most important factors Central Composite Design (CCD) was used. The analysis of the results showed that the pH value and temperature of desorption were the most significant factors.
