摘　　要：电感耦合等离子体质谱法具有灵敏度高、速度快、线性范围宽等优点,可用于面料中微量元素的测定。通过微波消解法消解纺织面料,采用电感耦合等离子体质谱法(ICP-MS)测定纺织面料中的锗含量,建立了微波消解-电感耦合等离子体质谱法测定面料中锗元素含量的方法。研究结果表明,锗元素在0.2~40.0μg/L范围内线性关系良好(R2=0.999 9),方法的检出限为0.02 mg/kg,不同含量加标(0.02、0.04、0.08、0.16 mg/kg)回收率在82.6%~107.8%,相对标准偏差3.0%~9.3%(n=6)。该方法具有灵敏度高、精密度好、检出限低的优点,能够用于面料中锗元素含量的测定。Inductively coupled plasma mass spectrometry （ ICP-MS） has the advantages of high sensitivity, fast speed, and wide linear range, and can be used for the determination of trace elements in fabrics. In this study, digestion of fabrics is carried out with microwave digestion method, determination of Ge content in fabrics is conducted with inductively coupled plasma-mass spectrometry, and a method is established for the analysis of Ge content in fabrics by inductively coupled plasma mass spectrometry （ICP-MS） with microwave digestion. Research results show that Ge has a good linear relationship within the range of 0. 2 -40. 0 ｜JLg/L（i？2 =0. 999 9） ; the limit of detection （ LOD） of the method is 0.02 mg/kg ; the recoveries of Ge spiked to real sample range from 82.6% to 107. 8% （0.02,0.04,0. 08,0. 16 mg/kg） , and the relative standard deviation （RSD） is 3. 0% -9. 3% （n =6）. The method has the advantages of high sensitivity, high precision and low detection limit, which is suitable for determination of Ge content in fabrics.
