adsorbent resin, Chromabond (HR-P) was purchased from Macherey Nagel.
As illustrated in Figure 3, 2% divinylbenzene
crosslinked Merrifield resin was allowed to react with 2 under [S.sub.N]2 conditions to form 3.
* withdrawal of 16 OESs: clichlorvos, divinylbenzene
(mixed isomers), furfuryl alcohol (FA), glycerol trinitrate, nitrogen dioxide, nitrogen monoxide, sulphur dioxide, propylene dinitrate, ethylene dinitrate, subtilisins, sulphuric acid and five glycidyl ethers (2,3-epoxpropyl ethers).
) has been sulfonated by a variety of methods to afford samples with different sulfur contents.
Separation of soluble sugars was performed on a CarboPac PA-100 analytical column (4 x 250 mm, styrene cross-linked with divinylbenzene
bed, size 8.5 [micro]m) coupled to a CarboPac PA100 pre-column (Dionex, Sunnyvale, CA) at a flow rate of 1 mL [min.sup.-1].
furnishes an EPA approved turbidimeter calibration standard that is a cross-linked divinylbenzene
styrene stable suspension polymer in a pure water media.
Dow Plastics, Midland, Mich., recently began offering a new grade of divinylbenzene
(DVB) monomer with 63% activity that can be used to formulate fast-curing Class-A automotive SMC and BMC.
(DVB, 55%, a crosslinking agent), 2,2'-Azobis(2-methylpropionitrile) (AIBN, 98%), Sorbitan monooleate (Span[R] 80) and anhydrous Calcium chloride (Ca[Cl.sub.2]) were purchased from Sigma-Aldrich.
The coating on the fiber can consist of a variety of materials, including carbowax template resin, polydimethylsiloxane, polydimethylsiloxane divinylbenzene
, polyacrylate, carboxen polydimethylsiloxane, and carbowax divinylbenzene
In this respect, the most effective analytical technique for the determination of perfluorinated alkyl acids (PFAs) in drinking water consists of extraction procedures by offline solid-phase extraction (SPE) cartridge containing polystyrene divinylbenzene
followed by elution in methanol, concentration to dryness with nitrogen, injection and analysis using liquid chromatography/tandem mass spectrometry (LC/MS/MS) [20-22].
