| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
