ASTM D7485-2016 0524 Standard Test Method for Determination of Nonylphenol p-tert-Octylphenol Nonylphenol Monoethoxylate and Nonylphenol Diethoxylate in Environmental Waters by Liq.pdf

1、Designation: D7485 16Standard Test Method forDetermination of Nonylphenol, p-tert-Octylphenol,Nonylphenol Monoethoxylate and Nonylphenol Diethoxylatein Environmental Waters by Liquid Chromatography/TandemMass Spectrometry1This standard is issued under the fixed designation D7485; the number immediat

2、ely following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This tes

3、t method covers the determination of nonylphe-nol (NP), nonylphenol ethoxylate (NP1EO), nonylphenol di-ethoxylate (NP2EO), and octylphenol (OP), extracted fromwater utilizing solid phase extraction (SPE), separated usingliquid chromatography (LC) and detected with tandem massspectrometry (MS/MS). Th

4、ese compounds are qualitativelyand quantitatively determined by this method. This methodadheres to single reaction monitoring (SRM) mass spectrom-etry.1.2 The method detection limit (MDL) and reporting limit(RL) for NP, NP1EO, NP2EO, and OP are listed in Table 1.1.3 The values stated in SI units are

5、 to be regarded asstandard. No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices

Commercial NP is produced by thereaction of phenol with commercial nonene. Commercialnonene is not simply a linear C9H18 alpha olefin; it is acomplex mixture of predominantl

10、y nine-carbon olefins, calledpropylene trimer, containing no linear isomers. This synthesisresults in a mixture of various branched nonylphenol isomersrather than a discrete chemical structure. The branched nonylgroup is positioned predominantly in the para position on thephenol ring.3.2.3 octylphen
