Application of graphene oxide- magnetic nanoparticle for solid phase extraction of trace amounts of cadmium ions in environmental samples
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 scanni...
متن کاملMagnetic Solid Phase Extraction of Triazine Herbicides from Environmental Aquatic Media using Polyaniline/ Fe3O4 Nanocomposite
Polyaniline/Fe3 O4 magnetic nanoparticles were synthesized and employed as a sorbent for the magnetic solid phase extraction (MSPE) of seven triazine herbicides from environmental water samples. The properties of the prepared magnetic sorbent were characterized using field emission-scanning electron microscopy (FE-SEM), fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetome...

Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) spectrometry and vibrat...
متن کاملChemical Modification of Nanosilica Toward Dispersive Solid Phase Extraction of Trace Triazine Herbicides from Environmental Water Samples
An easy and fast pathway in preparation of organo-functionalized silica in nanosize range withphenyl-terminated group via co-condensation method is reported. Fourier transform infrared(FTIR) spectra confirmed the grafting process and scanning electron microscopy (SEM) imagecorroborated formation of nanosized material. Applicability of phenyl-modified nanosilica wasexamined as a sorbent in dispe...
متن کاملSolid Phase Extraction Using Modified Magnetic Iron Oxide Nanoparticles for Extraction and Spectrofluorimetric Determination of Carvedilol in Human Plasma Samples
A new analytical approach was developed involving magnetic solid–phase extraction and spectrofluorimetric determination of carvedilol in human plasma samples. A plasma sample was prepared and adjusted to pH 8.2–10, then carvedilol was quickly extracted using iron oxide magnetic nanoparticles modified by the surfactant cetyltrimethylammonium bromide and determined to apply spectrofluorimetry...
