Problems solved by technology

Finally, because the nonionic surfactants used in industry such as APEOs are usually complex mixtures, it is difficult to buy standards for all compounds, and the synthesis and characterization of polymer monomer standards are usually expensive, so unit resolution is used. Mass spectrometry has limitations for target analysis of all possible polymers mentioned above

Abstract

The invention discloses a method for quickly screening and accurately confirming alkylphenol ethoxylates in textiles. The method includes preparing alkylphenol ethoxylates extract liquor; carrying out high-performance liquid phase chromatographic separation and high-resolution mass spectrometric determination; carrying out screening and confirming analysis, determining that samples are positive samples if high-performance liquid phase chromatographic / high-resolution mass spectrometric data of the samples simultaneously meet conditions that the allowable deviation of chromatographic peak retention time is + / -0.2 min, the allowable deviation of accurate mass numbers of parent ions is + / -5 ppm, matching thresholds of isotopic distribution of the parent ions are higher than 60% and the allowable deviation of accurate mass numbers of fragment ions is + / -5 ppm, or determining that the samples are negative samples if the high-performance liquid phase chromatographic / high-resolution mass spectrometric data of the samples do not simultaneously meet the conditions; extracting the accurate mass numbers of the parent ions in the extract liquor, computing peak areas of chromatographic peaks, comparing the extract liquor to standard solution and carrying out quantitative analysis. The method has the advantages that the method is in high-throughput detection modes for acquiring analysis results for diversified compounds in the short-chain and long-chain alkylphenol ethoxylates at one step by means of one-step treatment and one-step sample injection, accordingly, the detection efficiency can be improved, and the detection cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of textile detection, in particular to a method for rapidly screening and accurately confirming alkylphenol polyoxyethylene ether in textiles. Background technique [0002] Alkylphenol polyoxyethylene ethers (APEOs) nonionic surfactants have the characteristics of stable properties, acid and alkali resistance and low cost, and are often used as emulsifiers, finishing agents, penetrating agents, detergents, etc. During processing, washing, bleaching and dyeing. Among APEOs, nonylphenol ethoxylates (NPEOs) are the most used, accounting for about 80%; followed by octylphenol ethoxylates (OPEOs), accounting for more than 15-20%. Humans are exposed to APEOs through various routes, such as food intake, environment or skin contact. APEOs metabolites, such as nonylphenol (NP), octylphenol (OP) and APEOs with a low degree of polymerization, have been proven to have estrogen activity, interfere with human endocrine,...
