With the continuous improvement of the level of consumption, people's awareness of environmental protection of textiles is also enhanced, the possible existence of toxic substances in textile damage to consumer health, has drawn more and more attention. Promulgated by the International Textile Ecology Study and detection of association Oeko -texstandard 10 0 of textiles in pentachlorophenol (PCP) Limited made a clear
Tengzhou City Xiangying Analysis Technology Co., Ltd. of tecp samples with potassium carbonate solution after extraction, and then acetic anhydride acetylation and extracted with n-hexane, and determination chromatography with electron capture detector 7990GC-ECD by gas XiangyingGC7990plus chromatography, external standard method for quantitative. Discusses several kinds of natural fiber fabric sample extraction, acetylation and other conditions, method detection limit of 0.02 mg / kg, and the recovery rate of 88.4% to 10 2 6%, RSD is less than or equal to 4.0%.
随着消费水平的不断提高 ,人们对纺织品的环保意识亦在增强 ,纺织品中可能存在的毒
性物质对消费者健康造成的损害 ,已越来越引起人们的重视。国际纺织品生态学研究与检测协会颁布的Ｏｅｋｏ -ｔｅｘｓｔａｎｄａｒｄ 10 0对纺织品中五氯苯酚(ＰＣＰ)的限量做出了明确
滕州市翔鹰分析技术有限公司对样品中的TeCP用碳酸钾溶液提取后 ,再用乙酸酐乙酰化 ,以正己烷提取 ,用XiangyingGC7990plus气相色谱 -电子俘获检测器 (7990GC-ECD)测定 ,外标法定量。探讨了几种天然纤维纺织品试样提取、乙酰化等条件 ,方法的检出限 0 .0 2mg/kg ,加标回收率88.4%～ 10 2 .6 % ,RSD≤ 4.0 %。
