GB/T 23322-2009 in English

《GB/T 23322-2009纺织品 表面活性剂的测定 烷基酚聚氧乙烯醚》由TC209（全国纺织品标准化技术委员会）归口，TC209SC1（全国纺织品标准化技术委员会基础标准分会）执行，主管部门为中国纺织工业联合会。
本标准规定了纺织品中烷基酚聚氧乙烯醚（ＡＰ�睿牛希��睿剑病�１６）的反相高效液相色谱（反相ＨＰＬＣ）
筛选方法、正相高效液相色谱（正相ＨＰＬＣ）检测方法和液相色谱?串联质谱（ＬＣ?ＭＳ／ＭＳ）检测方法。
本标准适用于各类纺织产品。

1 Scope

This standard specifies the screening method through reversed-phase high performance liquid chromatography (RHPLC), the determination method through normal phase high performance liquid chromatography (N-HPLC) and liquid chromatography - tandem mass spectrum (LC-MS/MS) all regarding alkylphenol polyoxyethylene (APnEO, n=2~16 ) in textiles.
This standard is applicable to various textile products.
Note: The general formula for molecular structure of APnEO is: R-C6H4-(OC2H4)nOH. The “APnEO” in this standard refers to common octaphenyl polyoxyethylene ether [OPnEO, C8H17-C6H4-(OC2H4)nOH] and nonylphenol polyoxyethylene ether [NPnEO, C9H19-C6H4-(OC2H4)nOH].

2 Principle

Extract APnEO in sample through Soxhlet extraction method with methyl alcohol serving as the extraction solvent, and after having concentrated and purified the extracting solution, determine such extracting solution with high-performance liquid chromatograph equipped with fluorescence detector or through liquid chromatography - tandem mass spectrum, then quantify with external standard method.
