Chemical 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 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...
متن کاملApplication 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 کاملUse of solid phase extraction for speciation of selenium compounds in aqueous environmental samples
The performance and optimization of an anion exchanger phase (SAX) in line with a hydrophobic phase (C18) was studied for the preconcentration of selenite [Se(iv)], selenate [Se(vi)], dimethylselenide (DMSe), dimethyldiselenide (DMDSe), diethylselenide (DESe) and diethyldiselenide (DEDSe), using a GC-MS system to characterize the different selenium species. Optimum separation and preconcentrati...
متن کاملSpectrophotometric determination of iron in environmental and food samples using solid phase extraction.
A simple, selective and highly sensitive extraction method has been developed for the determination of iron(II) spectrophotometrically after solid phase extraction. The absorbance is measured at λmax 644 nm. Beer's law was obeyed up to 450 ng mL(-1) of iron. The molar absorptivity, Sandell's sensitivity, detection and quantification limits were calculated and found to be 1.09×10(5) L mol(-1) cm...
