From:Journal of Analytical Chemistry (Vol. 71, Issue 8) Peer-ReviewedUsing emulsion dispersive liquid--liquid microextraction preconcentration and injection of a large volume of an extract (10 [micro]L), the limits of chromatographic-mass spectrometric detection of o-phthalic acid esters...
-
From:Journal of Analytical Chemistry (Vol. 70, Issue 1) Peer-ReviewedA novel ion imprinted polymer (IIP) material has been synthesized for mercury ion. The IIP material is applied to the solid phase extraction (SPE) of [Hg.sup.2+] from complex matrixes including water and fish samples....
-
From:International Journal of Analytical ChemistryPeer-ReviewedA selective and simple method for separation and preconcentration of zinc ions was developed by using dispersive liquid-liquid microextraction. Parameters that have an effect on the microextraction efficiency such as...
-
From:Oil Shale (Vol. 28, Issue 4) Peer-ReviewedPure ethanol and its mixtures with water were used as extraction solvents for two Israeli's oil shales. Using bioethanol-like mixtures to produce organic matter from oil shales made the extraction process...
-
From:Ground Water (Vol. 33, Issue 3) Peer-ReviewedA two-dimensional air flow model has been developed for determining the efficiency of soil vapor extraction (SVE) technology used in the cleanup of hydrocarbon-contaminated, unsaturated soil. Values obtained using the...

From:LC-GC North America (Vol. 31, Issue 2) Peer-ReviewedThis short review covers the use of ionic liquids (ILs) and polymeric ionic liquids (PILs) in solid-phase microextraction (SPME) and dispersive liquid-liquid microextraction (DLLME). Over the past decade, ionic...
-
From:Polymer Engineering and Science (Vol. 49, Issue 11) Peer-ReviewedNatural cellulose fibers with cellulose content, strength, and elongation higher than that of milkweed floss and between that of cotton and linen have been obtained from the stems of common milkweed plants. Although...
-
From:Journal of Analytical Chemistry (Vol. 72, Issue 9) Peer-ReviewedMagnetite nanoparticles coated with silica and hydrophobic octadecyl layers were successfully synthesized and used in magnetic solid phase extraction of tetracyclines from water samples. The magnetite nanoparticles...
-
From:Journal of Analytical Chemistry (Vol. 73, Issue 2) Peer-ReviewedA micelle-mediated separation/preconcentration technique was used for the determination of trace Cd(II) in solid and liquid samples by flame atomic absorption spectrometry. Cadmium ions reacted with ammonium pyrrolidine...

From:Nature (Vol. 491, Issue 7423) Peer-ReviewedNearly one hundred years ago, the fermentative production of acetone by Clostridium acetobutylicum provided a crucial alternative source of this solvent for manufacture of the explosive cordite. Today there is a...
-
From:LC-GC North America (Vol. 28, Issue 2) Peer-ReviewedThe extraction and analysis of semi-volatile organic (SVOC's) compounds can be problematic due to the wide range of analyte types and polarities. UCT has developed a unique C18 bonded silica sorbent that provides the...
-
From:Chemical EngineeringPeer-ReviewedDepartment Editor: Scott Jenkins Liquid-liquid extraction is a common mass-transfer operation in which a target solute material is transferred from a feed phase into a solvent. The process is used in a number of...
-
From:Oil Shale (Vol. 32, Issue 3) Peer-ReviewedA short overview of the previous works concerning oil extraction from Jordanian oil shale is presented. The results of the systematic experimental study obtained in this work on the effects of temperature...
-
From:Canadian Journal of Chemistry (Vol. 88, Issue 4) Peer-ReviewedThe Canadian Environmental Protection Act, 1999 (CEPA, 1999) requires the Canadian government to categorize all substances on the Domestic Substances List (DSL). Under the Chemicals Management Plan, the Government of...
-
From:Forensic Science International (Vol. 162, Issue 1-3) Peer-ReviewedAbstract A new and sensitive method to determine ticlopidine in whole human blood using proadifen as the internal standard (IS) is described. The analyte and IS were extracted by solid-phase extraction using Oasis...
-
From:Forensic Science International (Vol. 161, Issue 1) Peer-ReviewedAbstract High performance liquid chromatography with diode array detection (HPLC-DAD) was used to develop a method for the simultaneous determination of morphine, codeine, 6-acetylmorphine (6AM), cocaine,...
-
From:Biochemistry (Moscow) (Vol. 80, Issue 3) Peer-ReviewedChromatin in rat liver nuclei under conditions of low ionic strength (20-25 mM) and [[Mg.sup.2+]] from 2 to 5 mM has a condensed structure (100-200 nm globules) and gives the same CD signal (320-340 nm) at interaction...
