Magnetic natural zeolite analcime nanoparticles modified by N-Phenylaza-15-Crown-5 were prepared and used as an adsorbent for extraction and preconcentration of cadmium 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), X-ray diffraction (XRD) spectrometry and vibrating sample magnetometer (VSM) were used to characterize the adsorbent. The MSPE conditions were optimized. The detection limit of 1.9ngL−1 was obtained. The linear range was 0.005–0.715ngmL−1 for cadmium. The relative standard deviations of the method for eight replicate determination of 0.04ngmL−1 of Cd (II) was ±2.8%. The method was applied for the determination of target ion in different samples with high recoveries.
