摘　　要：建立了一种基于电感耦合等离子体原子发射光谱法(ICP-AES)测定银内胆水杯中6种有害元素(砷、镉、铬、镍、铅和锑)迁移量的方法。结果表明,待测元素在标准曲线浓度范围内均呈良好线性关系,加标回收率86.1%~103.3%,相对标准偏差(RSD)均小于5%。在酸性迁移条件下,部分样品可检出一定量的锑元素迁移量,锑迁移量为0.00868~0.0304 mg/dm2。可为银餐具安全评价提供技术支持。A method based on inductively coupled plasma optic emission spectrometry(ICP-OES)for the determination of the migration of six harmful elements(As,Cd,Cr,Ni,Pb and Sb)in the silver tank cup was established.The results showed that the elements to be tested had a good linear relationship in the concentration range of the standard curve,the recovery rate was 86.1%~103.3%,and the relative standard deviate(RSD)was less than 5%.Under the condition of acid migration,a certain amount of antimony migration can be detected in some samples,and the measured antimony migration was 0.00868~0.0304 mg/dm2.The results of this study can provide technical support for the safety evaluation of silver tableware.
