摘　　要：采用干法灰化法处理银纤维纺织品试样，结合ICP-AES法对样品中的铅、镉、砷、铜、钴、镍、铬等重金属含量进行测定。方法元素检出限为0.0006~0.0129μg/mL，相对标准偏差1.96%~8.90%，各元素的加标回收率为81.3%~101.2%，达到了便捷、准确、可靠的要求，可以满足日常检测的需要。The method of using dry- ashing and determination of the content of heavy metals including Pb,Cd,As,Cu,Co,Ni and Cr in silver fiber textiles by ICP-AES were established.The element detection limits of the method were 0.0006- 0.0129 μ g/mL with low relative standard deviation. The elements recoveries of standard addition method were 81.3%-101.2%.
