摘　　要：建立无纺布中8种金属元素的微波消解-电感耦合等离子体质谱的分析方法。应用Cs内标，仪器信号漂移和样品的基体效应能得到很好的补偿。对所测定元素，方法的检出限为0.01～0.10ng／mL，回收率为82％-116％，RSD小于10％（n=5）。A method for the determination of 8 elements in non woven fabric by microwave digestion-ICP-MS was reported in this paper.Cs,the internal standard element, can compensate the drift of MS-signals and also reduce matrix effects in analytical solution.For all analyte elements, the detection limits are in the range of 0.01-0.10ng/ mL,the recoveries are in the range of 82%-116%,the relative standard deviations are less than 10% （n=5）.
