纺织品中可萃取重金属检测的半定量方法

Research on Semi-quantitative Methods of Detection of Extractable Heavy Metals in Textiles

本文采用带八级杆碰撞反应池系统（Octopole Reaction System）的电感耦合等离子体质谱仪（ICP－MS），建立了一套完整、快速检测纺织品中可萃取重金属元素的半定量方法。对样品进行半定量分析和加标回收试验，结果表明：该套方法可以有效地消除干扰，实现对纺织品中多种可萃取重金属的快速检测，测定结果与实际标准溶液的偏差在10％以内，加标回收率为86．2％～104．2％。

inductively Coupled Plasma Mass Spectrometer （ICP-MS） with Octopole Reaction System （ORS） was adopted to establish a short-term measuring method of definite quantitative determination of extractable heavy metal in textiles in this paper. Semi-quantitative analysis and standard addition recovery were practised on samples. It was showed that this method could test several kinds of extractable heavy metal and minimize the disturbances. The deviation between testing results and standard solution was less than 10%, and the standardized recovery was in the range of 86.2%-104.2%.
