SOXHLET EXTRACTION OF PENTACHLOROPHENOL FROM SOIL WITH IN SITU DERIVATIZATION
(Sociedad Chilena de Química, 2001)
Derivatization and rapid GC-MS screening of chlorides relevant to the chemical weapons convention in organic liquid samples
(Royal Society of Chemistry, 2020-04)
A simple derivatization technique was developed for the analysis of seven Schedule 3 chemicals and one Schedule 2 chemical listed in the Chemical Weapons Convention (CWC). Phosgene, phosphorus oxychloride, phosphorus ...
Preparation and characterization of three different derivatized potato starches
(Springer/plenum Publishers, 2012-11-07)
The use of native starch as a thermoplastic polymer is limited by its fragility and high water absorption. Due to the presence of several hydroxyl groups in its structure, water acts as a natural plasticizer of starch, ...
An alternative LC-UV procedure for the determination of prochloraz residues in fruits
(2005-03-01)
An alternative method using liquid chromatography with UV detection for the determination of prochloraz as 2,4,6-trichlorophenol in mango, papaya and orange is described. Ethyl acetate, acetone and dichloromethane were ...
Bio-nanocomposites based on derivatized potato starch and cellulose, preparation and characterization
(Springer, 2013-06)
The use of native starch as a thermoplastic polymer is limited by its fragility and high moisture absorption. Native potato starch was derivatized using different agents in order to reduce its hydrophobicity. A reduction ...
On-line derivatization with on-line coupled normal phase liquid chromatography-gas chromatography using the through oven transfer adsorption desorption interface: Application to the analysis of total sterols in edible oils
(Elsevier Science, 2012-07)
In the present work on-line derivatization is combined with on-line normal phase liquid chromatography-gas chromatography (NPLC-GC) to analyze total sterols in edible oils. The method uses the TOTAD interface with an ...
General Quantum-Based NMR Method for the Assignment of Absolute Configuration by Single or Double Derivatization: Scope and Limitations
(American Chemical Society, 2018-10)
The determination of the absolute configuration of chiral alcohols and amines is typically carried out with modified Mosher methods involving a double-derivatization strategy. On the other hand, the number of robust and ...
Analysis of citrulline and metabolic related amino acids in plasma by derivatization and RPLC. Application of the extrapolative internal standard calibration method
(Elsevier Science, 2016-11)
We propose to apply the extrapolative internal standard calibration method (EISM) for quantitative analysis of citrulline and other metabolically related amino acids in plasma by pre-columnderivatization, liquid chromatography ...
Magnetic nanohydrogel obtained by miniemulsion polymerization of poly (acrylic acid) grafted onto derivatized dextran
(Elsevier B.V., 2017-12-15)
This study describes the synthesis of magnetic nanohydrogels by miniemulsion polymerization technique. Dextran was derivatized by the glycidyl methacrylate to anchor vinyl groups on polysaccharides backbone, allowing its ...
Determination of glyphosate and aminomethylphosphonic acid in aqueous soil matrices: A critical analysis of the 9-fluorenylmethyl chloroformate derivatization reaction and application to adsorption studies
(Wiley-VCH Verlag, 2014)
© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.The assessment of the environmental fate of glyphosate and its degradation product (aminomethylphosphonic acid) is of great interest given the widespread use of the herbicide. ...
