摘　　要：建立了棉花纤维中铬、钴、镍、铜、砷、镉、锑、铅8种重金属元素的测定方法,并对国内外183个不同产地的棉花纤维样品中8种重金属元素的含量进行测定和结果分析比较。样品采用微波消解,以电感耦合等离子体质谱法同时测定8种重金属元素的含量。结果显示,国内外棉花纤维中均存在一定量的重金属元素,但总体含量水平较低,说明国内外棉花纤维中这8种重金属元素的含量在安全范围内。The method to determine the trace of Cr,Co,Ni,Cu,As,Cd,Sb,Pb in cotton fibers was established,and 8 heavy metals in 183 cotton fibers from different habitats were determined and compared.The samples were digested by microwave,and the levels of 8 heavy metals were determined by ICP-MS.Results showed that there are a certain amount of heavy metals in cotton fiber at home and abroad,but the overall level is low. It is demonstrated that the levels of 8 heavy metals in cotton fiber at home and abroad are safe.
