1 Scope

This part of SN/T 1850 specifies high performance liquid chromatography-mass spectrometry for alkyl phenols and alkyl phenol ethoxylates in textiles. test methods. This section applies to the determination of alkylphenols and alkylphenol ethoxylates in textiles.

2 Terms and definitions

The following terms and definitions apply to this part of the SN/T 1850. 2.1 The molecular structure of the alkylphenols is. R-C6H4-OH. This class of substances, commonly found in textiles, is octylphenol (C8H17- C6H4-OH, abbreviated as OP) and nonylphenol (C9H19-C6H4-OH, abbreviated as NP). 2.2 The molecular structure of the alkylphenol ethoxylates is. R-C6H4-(OC2H4)nOH. This type of substance is common in textiles. Octylphenol polyoxyethylene ether (C8H17-C6H4-(OC2H4)nOH, referred to as OPEO) and nonylphenol polyoxyethylene ether [C9H19-C6H4- (OC2H4)nOH, referred to as NPEO]. Alkylphenol ethoxylates can be used as surfactants in textiles, and alkylphenols are alkylphenol ethoxylates. Degradation products.

3 Principle

The sample was extracted by Soxhlet using methanol as the extraction solvent, the extract was concentrated, and the membrane was filtered and then subjected to high performance liquid chromatography-mass spectrometry. Conduct qualitative and quantitative analysis.

4 reagents and materials

Unless otherwise specified, only analytically pure reagents and distilled or deionized water or water of comparable purity were used in the analysis. 4.1 Methanol. Chromatographically pure. 4.2 Acetonitrile. chromatographically pure. 4.3 Octylphenol standard (purity. 97%). 4.4 Nonylphenol standard (purity. technical). 4.5 Octylphenol polyoxyethylene ether standard (purity. extra grade pure). 4.6 Nonylphenol ethoxylate standard (purity. ≥99.0%). 4.7 Alkylphenol standard stock solution. accurately weigh the appropriate amount of octylphenol (4.3) and nonylphenol (4.4) standards, with methanol (4.1) Prepared as a standard stock solution at a concentration of 10 mg/mL. 4.8 Alkylphenol polyoxyethylene ether standard stock solution. accurately weigh the appropriate amount of octylphenol polyoxyethylene ether (4.5) and mercaptobenzene Phenol polyoxyethylene ether (4.6) standard was prepared with methanol (4.1) as a standard stock solution at a concentration of 10 mg/mL. ......
