| 中文摘要: |
| 采用硝酸-过氧化氢消解体系,及高压密闭微波技术处理塑料包装材料,建立了电感耦合等离子体质谱法同时测定塑料包装材料中铅、镉、砷、铬、锑、汞、硒、钡、镍、锡、锶、铊多种有毒有害元素的方法。 方法的检出限为0.0 2~0.2 0μ g / L,相对标准偏差(RS D)小于1 0%,加标回收率为8 8.0%~1 1 7.0%。 该方法简单、快速、灵敏、准确度好。 |
| 英文摘要: |
| Plastic packaging materials were digested by mixed acids of nitric acid and hydrogen peroxide solution using high pressure and closed microwave digestion technology. A method for the determination of Pb, Cd, As, Cr, Sb, Hg, Se, Ba, Ni, Sn, Sr and Tl in packaging materials by ICP-MS was established. The detection limits are in the range of 0.02～0.20 μg/L; the relative standard deviations are less than 10%; the recoveries are in the range of 88.0%～117.0%. The results proved that this method is simple, accurate, and reliable. |
