中文摘要:
      手工纸样品采用硝酸-过氧化氢,190℃微波辅助加热消解,采用电感耦合等离子质谱法(ICP-MS)同时测定传统手工纸中砷、铅、铬、镍、锑和镉6种重金属元素含量。使用碰撞技术消除ArCl离子对砷的干扰。优化了反应电压(RPq)、碰撞气体流量等测试条件,6种元素仪器检出限在0.003 mg.kg-1~0.02 mg.kg-1之间,7次重复性相对标准偏差(RSD)在1.7%~2.6%,分别在样品中加标3mg.kg-1和7 mg.kg-1,回收率在88.9%~107.3%。6批次手工纸样品中有砷、铅、铬、镍和锑元素检出。方法检出限低、快速、准确,适用于传统手工纸中6种杂质重金属元素同时测定。
英文摘要:
      Samples of handmade paper was pretreated by microwave assisted digestion, and the contents of As, Pb, Cr, Ni, Sb and Cd in the handmade paper were determined by ICP-MS. Kinetic energy discrimination (KED) were used to overcome disturbance of ions,such as ArCl. The parameters of the test methods were optimized seriously, including RPq and affects of different Neb gas flow rate. Detection limits of the 6 elements were in the ranges of 0.003 mg.kg-1~0.02 mg.kg-1, 3.0mg.kg-1 and 7.0 mg.kg-1 mix standard solution were added in the samples respectively. Values of recovery and RSD’s were found in the range of 88.9%~107.3% and 1.7%~2.6%. As, Pb, Cr, Ni and Sb, were detected in some of the samples. The method is fast, accurate and has a low detection limit. It is suitable for determination of impurity metal ions in handmade paper
