摘　　要：用石墨炉原子吸收光谱法测定不锈钢食具容器的Cr、Ni、Cd、Pb的迁移量。研究了样品前处理的选择，不同样品类型的影响，并考察了其它元素对Cr、Ni、Cd、Pb测量的化学干扰．用本实验方法对样品进行了测量，结果满意．其元素Cr、Ni、CA、Pb的检测限达到0．18—0．89μg/L，方法回收率为8012％-90．6％，相对标准偏差RSD为2．1％-8．9％，方法的精密度和重复性基本令人满意，能满足实验室测定不锈钢食具容器铬、镍、镉、铅迁移量的要求。the migration of stainless steel food containers and detelxnination by graphite famace atomic absorption spectrometry ofCr, Ni, Cd, Pb. Study on the pretreatment of sample selection, effects of different sample rules, and the effects of the chemical interference of other elements on the Cr, Ni, Cd, Pb measurement. The measurement, the samples were used in this experiment method with satisfactory results. To detect the elements Cr, Ni, Cd, Pb limit of 0.18 - 0.89 μg/L, the recovery rate is 80.2%-90.6%, the relative standard deviation of RSD is 2.1% - 8.9%, the precision and repeatability of the basic method is satisfied, it can satisfy the laboratory detennination of stainless steel food containers and chromium, nickel, cadmium, lead migration requirements.
