石墨炉原子吸收法测定纯棉纺织品中重金属的含量

DETERMINATION OF HEAVY METALS CONTENT IN PURE COTTON FABRICBY GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROMETRY(GFAAS)

介绍了利用石墨炉原子吸收分光光度计测定纯棉纺织品中Cr、As、Pb、Cd等重金属总量的方法.结果表明:不同工艺阶段的产品重金属含量有较大差异,其中,总铬含量(6.9～118.4mg/kg)远远超过规定限量(1.0～2.0mg/kg),应引起厂家对绿色纺织品中有害金属控制的重视,以提高我国加入WTO后纺织品在国际市场上的竞争能力.

Determination of total ammount of heavy metals including Cr,As,Pb,Cd,etc. in pure cotton fabric by GFAAS was described. The result indicated that heavy metals content varied considerably with process stage. Among which, total content of Cr(6.9～118.4mg/kg) far exceeded the regulated limit(1.0～2.0mg/kg). This means that the textile manufacturers of our country should attach great importance to the control of heavy metals in green textile so as to raise our international competition power after our accession to WTO.
