Özet

The present study describes a facile and environmentally friendly hydrothermal method for the fabrication of metal decorated silica-based core-shell magnetic nanocomposite M@Si-MNCs, applied as a sustainable coating material for the solid-phase microextraction of toxic cadmium ions. M@Si-MNCs were characterized by scanning electron microscopy, X-ray-diffraction, Fourier transform infrared spectroscopy and Brunauer-Emmett-Teller analyzer. Relevant parameters have been studied to obtain maximum recovery, including pH, adsorbent dosage, model solution volume, - adsorption and desorption time, and matrix effects. The developed method obtained excellent linearity from 50 to 500 mu g/L with a limit of detection of 1.2 mu g/L and a limit of quantification of 4.1 mu g/L. The new method was applied for separation, preconcentration and determination of cadmium in environmental and tobacco samples.
