چکیده
In this work for the first time, Fe3O4@SiO2 core-shell nanoparticles functionalized with isatin groups as a magnetic nanosorbent was applied for the simultaneous extraction of trace amounts of cadmium (II). The characterization of this nanosorbentwas studied using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The effect of several factors such as pH, amount of sorbent, extraction time, type and volume of the eluent, sample volume, and sorption capacity. In the selected conditions, it was observed that the limits of detection were 0.11 ng mL−1 for Cd(II) and the maximum sorption capacity of this suggested magnetic nanosorbent was 120mg/g. Finally, the suggested procedure was applied for determination of cadmium (II) at trace levels in different water samples with satisfactory results.
