[Determination of triclosan and triclocarban in human nails by solid-phase extraction and ultra performance liquid chromatography-tandem mass spectrometry].

An analytical method was developed to simultaneously detect triclosan (TCS) and triclocarban (TCC) in human nails using solid phase extraction (SPE) with ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Nail clippings were digested by sodium hydroxide, and then concentrated and purified with C18 cartridges. Chromatographic separation was performed on a Waters ACQUI...

Hollow-Fibre-Supported Dispersive Liquid-Liquid Microextraction for Determination of Atrazine and Triclosan in Aqueous Samples

We report the application of the dispersive liquid-liquid microextraction coupled to hollow-fibre membrane-assisted liquid-phase microextraction and its application for extraction of atrazine and triclosan. Under optimum conditions, namely, 25 μL of a 1 : 4 chlorobenzene : ethyl acetate mixture dispersed in 1 mL of aqueous sample, 10% (m/v) NaCl, a magnetic stirrer speed at 600 rpm, and 10 minu...

Extraction and Detection of Pentobarbital in Soil by Solid Phase Extraction and Liquid Chromatography / Mass Spectrometry

Expression analysis of extracellular proteins from Phanerochaete chrysosporium grown on different liquid and solid substrates

White-rot fungi secret a large number of hydrolytic and oxidative enzymes for degradation of lignocellulosic material. The sequencing of the genome of the white-rot fungus Phanerochaete chrysosporium has facilitated the characterization of its complete extracellular proteome. P. chrysosporium was grown on liquid medium, containing glucose, cellulose or wood chips as the carbon source, and also ...

Inferences About Radionuclide Mobility in Soils Based on the Solid/Liquid Partition Coefficients and Soil Properties

To assist transport modeling in assessments of the radiological impact of a geological repository for radioactive wastes, the mobility of various elements was studied in arable and wetland soils in the Forsmark region, Sweden. Pore water and total element contents were determined for five types of unconsolidated deposits (regolith), spanning a wide range of soil properties with respect to pH an...
