1 Scope
SN/T 1850 provisions of this part of the normal phase HPLC textiles alkyl phenols and alkyl phenol polyoxyethylene ethers
And liquid chromatography - tandem mass spectrometry.
This section applies to the determination of textiles alkyl phenols and alkyl phenol polyoxyethylene ethers.
Note. The molecular structure of alkyl phenols of the general formula. R-C6H4-OH, referred to as AP. AP in this section refers to common octylphenol [OP, C8H17-
C6H4-OH] and nonylphenol [NP, C9H19-C6H4-OH]. Alkylphenol ethylene oxide ether of molecular structure of the general formula. R-C6H4-
(OC2H4) nOH, referred APnEO. APnEO in this section refers to common octyl phenol ethoxylates [OPnEO, C8H17-C6H4-
(OC2H4) nOH] and nonylphenol ethoxylates [NPnEO, C9H19-C6H4- (OC2H4) nOH].
Principle 2
Samples Soxhlet extraction with methanol, and the extract was concentrated and purified using a fluorescence detector with high performance liquid chromatography or liquid chromatography -
Tandem mass spectrometer, external standard.
