纺织品中烷基酚聚氧乙烯醚检测标准修订的必要性

Necessity for standard revision of determination of alkylphenol ethoxylates in textiles

介绍了国际上纺织品表面活性剂烷基酚聚氧乙烯醚(APEO)检测方法概况;通过对国内外纺织品表面活性剂APEO检测标准进行对比分析,结合国内现状,论述了我国纺织品表面活性剂APEO检测标准与国际通用标准存在的差距:我国纺织品中APEO的检测采用的是GB/T23322—2009或行业标准的甲醇索氏提取法,相比于国际通用标准中的有机溶剂超声萃取法,具有耗时长,方法繁琐等缺点;论证了我国纺织品中APEO的检测方法—快速筛选法的可行性,该方法具有操作简单,试剂消耗量小,有机试剂使用量少,且具有较低的检测限和较高的结果准确性和重现性;建议我国纺织品中APEO的检测方法采用快速筛选法,并尽快修订完善纺织品中APEO的检测方法标准和实施。

The general situation of the determination methods of alkylphenol ethoxylates(APEO),a surfactant for textiles,was introduced in the world.The gap between the China and international general standards of APEO determination was described through comparative analysis.Compared with the ultrasonic extraction method of organic solvent in the international general standard,the determination of APEO in textiles by methanol Soxhlet extraction method based on GB/T 23322-2009 or industry standard in China has the disadvantages of time-consuming and cumbersome operations.The feasibility fo rapid screening method for APEO in textiles was demonstrated in China,which has the advantages of simple operation,low consumption of reagents,less use of organic reagents,low detection limit,high accuracy and reproducibility.It was suggested that the rapid screening method should be adopted in the determination of APEO in textiles in China and the standard for the determination method of APEO in textiles should be revised and implemented as soon as possible.
