Pesticide extraction efficiency of two solid phase disk types after shipping.
An interlaboratory study was conducted to compare pesticide recovery from Empore C(18) and Speedisks C(18)XF solid phase extraction disks after shipping. Four pesticides were used for the comparison of the two disk extraction materials: atrazine, diazinon, metolachlor, and tebuconazole. These pesticides were chosen to provide a range of physiochemical properties. Water samples were extracted on...
متن کاملSynthesis and Application of Novel Modified Magnetic Nanocomposite for Solid Phase Extraction of Thallium(I) Ions
In this paper, magnetically multiwalled carbon nanotubes (MMWCNTs) nanocomposite modified by methyl-2-[2-(2-2-[2-(methoxycarbonyl) phenoxy] ethoxyethoxy) ethoxy] benzoate was applied for magnetic solid-phase extraction (MSPE) of thallium(I) ions. Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) spectrometry and vibrat...
متن کاملHeadspace Solid Phase Microextraction in Pesticide Residues Analysis: 1. Optimisation of Extraction Conditions
The method of headspace solid phase microextraction (HS/SPME) was successfully used in a simultaneous multicomponent analysis of hexachlorobenzene (HCB), tefluthrin, heptachlor, aldrin, chlorpyrifos, fenthion and bifenthrin in aqueous medium. Measurements were performed using a nonpolar polydimethyl siloxane (PDMS) fiber. Detection and quantification were done by gas chromatography/mass spectro...
متن کاملsolid phase extraction of pesticide residues in water samples: ddt and its metabolites
solid phase extraction (spe) cartridge embedded with octadecyl c18 chain bounded to silica particles were used for the isolation and trace enrichment of pesticides from water samples collected from cotton, rice growing and municipal areas. the eluents were analyzed with high performance liquid chromatography (hplc) using methanol (100%) as mobiles phase at different uv-visible wavelengths. ddt ...
متن کاملIntroduction to Solid-phase Extraction
We have a sample in front of us. It is of unknown composition, but we know that it is complex, containing anywhere from a few hundred to many thousand chemical components. It is of uncertain physical form perhaps it looks like a liquid, but it has solid particles floating in it. We think that a particular compound is present in that sample, somewhere and in some form, but we don't know how much...
