Abstract

IN THIS WORK, SOLID-PHASE EXTRACTION OF TRACE AMOUNTS OF CADMIUM FROM LARGE VOLUMES OF AQUEOUS SOLUTIONS WAS STUDIED. THE EXTRACTION WAS CARRIED OUT BY MEANS OF NON-MODIFIED FE3O4 NANOPARTICLES AS AN ADSORBENT AND THEN DETERMINED BY USING FLAME ATOMIC ABSORPTION SPECTROMETRY (FAAS) [1].SEVERAL EFFECTIVE PARAMETERS SUCH AS: PH, IONIC STRENGTH, AMOUNT OF ADSORBENT, TYPE AND CONCENTRATION OF ELUENT WERE OPTIMIZED BY USING ORTHOGONAL ARRAY EXPERIMENTAL DESIGN. THE ANALYTE IONS QUANTITATIVELY WERE ADSORBENT ON MAGNETIC FE3O4 NANOPARTICLES AND THEN MAGNETIC NANOPARTICLES (MNPS) WERE EASILY SEPARATED FROM THE AQUEOUS SOLUTION BY APPLYING AN EXTERNAL MAGNETIC FIELD, THUS, NO FILTRATION OR CENTRIFUGATION WAS NECESSARY [2-3]. AFTER EXTRACTION AND COLLECTION OF MNPS, THE ANALYTE IONS WERE ELUTED USING 1.0 MOL L-1OF HCL. UNDER THE OPTIMUM EXPERIMENTAL CONDITIONS, LINEARITY WAS MAINTAINED BETWEEN0.017-0.508 MG ML-1 FOR CADMIUM. DETECTION LIMITS AND RELATIVE STANDARD DEVIATION (N=10) WERE0.49 MGL-1 AND 1.11%, RESPECTIVELY. FINALLY, THE METHOD WAS SUCCESSFULLY APPLIED TO THE EXTRACTION AND DETERMINATION OF CADMIUM IONS IN SEVERAL WATER SAMPLES [4].
