摘　　要：以酸性汗液为萃取剂,基于电感耦合等离子体质谱(ICP-MS)法,建立了一种快速、准确测定涤纶长丝中可萃取重金属锑含量的方法。该方法检出限低达0.025μg/L;在锑浓度为(2.0~200.0)μg/L范围内线性关系良好,R2大于0.999;2.0,4.0,100.0低中高三个浓度的加标回收率在(90~115)%,准确度良好;RSD=1.1%,具有较好的精密度。A rapid and accurate method for the determination of extractable heavy metal antimony in polyester filament was developed based on inductively coupled plasma mass spectrometry(ICP-MS) with acid sweat as extractant. The detection limit of the method is as low as 0.025 μg/L;the linear relationship is good in the range of antimony concentration(2.0~200.0) μg/L with R2 greater than 0.999;the recovery rate of standard addition of 2.0, 4.0, 100.0 μg/L are in the range of(90~115)%, showing good accuracy;RSD=1.1 %, indicating good precision.
