Abstract
Abstract In this work, Fe3O4-graphene oxide nanocomposite (GO-Fe3O4) was prepared as effective absorbent for magnetic solid phase extraction (MSPE) of trace quantities of cadmium ions in environmental water and rice samples using 1, 2-dihydroxy anthraquinone-3-sulphonic acid, sodium salt (Alizarin red S) and flame atomic absorption spectrometry (FAAS). The GO-Fe3O4 was characterized by scanning electron microscopy (SEM) and X-ray powder diffraction (XRD). Various parameters affecting GO-Fe3O4 MSPE of cadmium have been investigated. Under the optimized experimental conditions, the limit of detection (LOD) for Cd2+ in the range of 1-50 ngL-1 were 0.21 and the relative standard deviation (RSDs, c=50 ngL-1, n=7) were 3.2 %. The developed GO-Fe3O4 MSPE-FAAS method has the advantages of rapidity, simplicity, good sensitivity, and it is suitable for the analysis of trace cadmium in samples with complex matrix.
