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.
The method for determining the total amount of heavy metals such as Cr, As, Pb and Cd in pure cotton textiles by graphite furnace atomic absorption spectrophotometer was introduced.The results showed that the content of heavy metals in the products of different technological stages was quite different, 6.9 ~ 118.4mg / kg) far exceeds the stipulated limit (1.0 ~ 2.0mg / kg), manufacturers should pay attention to the control of harmful metals in green textiles in order to improve our country’s competitiveness in the international market after joining WTO.
