Abstract: This study focused on the development of a magnetic solid phase extraction (m-SPE) method using Au-Fe3O4 as an adsorbent followed by GC-ToFMS analysis for the determination of organosulphur compounds (OSCs) in fuel samples. The m-SPE using Au-Fe3O4 NPs was preferred because of the low toxicity of the adsorbent1, high separation efficiency using external magnet2 and greater extraction selectivity between sulphur and Au atom3. The Au-Fe3O4 NPs were characterized using XRD, UV–Vis, TEM, SEM and FTIR. This method … Show more
