Development of an Analytical Method for Determining Tributyltin and Triphenyltin in Seawater, Sediment, and Mussel Samples Using GC-FPD and GC-MS – TOF
Analytical methods for speciation of targeted organotin compounds (TBT and TPT) in water samples using SPE cartridge and liquid-liquid extraction has been carried out. Also, sediment analysis using methanolacid digestion and acid-sonication extraction methods also were developed. Different parameters affecting extraction and peak resolution were optimized. Also, three derivatization procedures ...
متن کاملA single method for detecting 11 organophosphate pesticides in human plasma and breastmilk using GC-FPD.
Organophosphate (OP) pesticides are widely used for crop protection in many countries including Thailand. Aside from causing environmental contamination, they affect human health especially by over-stimulating of the neurotransmission system. OP pesticides, as with other non-persistent pesticides, degrade quickly in the environment as well as are metabolized quite rapidly in humans. Assessing h...
متن کامل[Determination of diphenyl and o-phenylphenol in agricultural products by GC/MS].
A simple determination method of diphenyl (DP) and o-phenylphenol (OPP) in agricultural products by GC/MS was examined. DP and OPP were extracted with ethyl acetate in the presence of anh. sodium sulfate. After addition of n-butanol, the extract solution was concentrated. Clean-up was achieved by shaking with graphitized bulk carbon (Supelclean ENVI-Carb). Addition of polyethylene glycol sharpe...
متن کامل[Simultaneous analysis of glyphosate and glufosinate in vegetables and fruits by GC-FPD].
A rapid analytical method for residues of the herbicide, glyphosate [N-(phosphonomethyl)glycine], glufosinate [DL-homoalanine-4-yl(methyl)phosphinic acid] and glufosinate metabolite (MPPA: 3-methylphosphinicopropionic acid) in vegetables and fruits was developed by improving the bulletin method of glufosinate. 50 mL of solution extracted with water (corresponding to 2 g of the sample) was loade...
متن کاملValidation of an Analytical Method for Determination of Benzo[a]pyrene Bread using QuEChERS Method by GC-MS
A fast and simple modified QuEChERS (quick, easy, cheap, rugged and safe) extraction method based on spiked calibration curves and direct sample introduction was developed for determination of benzo[a]pyrene (BaP) in bread by gas chromatography-mass spectrometry single quadrupole selected ion monitoring (GC/MS-SQ-SIM). Sample preparation includes extraction of BaP into acetone followed by clean...
