生态纺织品中有害金属元素的ICP-AES分析

Determination for Amount of Heavy Metal Results in Eco-Textile

以模拟酸性汗液萃取样品,以ICP-AES同时测定纺织品中Pb、As、Cu、Cr、Cd、Co、Ni和Sb 8种元素的含量。结果表明,本文采用的方法检出限在0．004-0．044mg／L之间,回收率为96．1％- 102．8％,相对标准偏差为0．65％-3．25％,能简便、快速、准确的测定纺织品中的多种重金属残留量。

The amounts of Pb,As,Cu,Cr,Cd,Co,Ni andSb in textile samples were extracted by imitated acid sweat, and determined by ICP-AES. The detection limits of 0. 004--0. 044mg/L, the recovery of 96. 1%--102. 8%,and the relative standard deviation （RSD） of 0. 65 %--3. 25 % were obtained. The method is convenient and rapid with good precision.
