Abstract
Magnetic silica nanoparticles modified by 3-[2-(2-aminoethylamino) ethylamino] propyl-trimethoxysilane (AAAPTS) and Salicylaldehyde were prepared and used as a new adsorbent for extraction and preconentration of copper ion through magnetic solid-phase extraction (MSPE) method. After adsorption, these ions were desorbed with nitric acid followed by the determination with electrothermal atomic absorption spectrometry. Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) spectrometry and vibrating sample magnetometer (VSM) were used to characterize the adsorbent. The MSPE conditions were optimized.
