| 中文摘要: |
| 目的 建立一种固相萃取净化-连续流动法测定纸质品中六价铬残留量的方法。方法 针对样品中的六价铬， 用pH为8.0的磷酸二氢钾缓冲溶液振荡萃取30 min， 经聚酰胺SPE柱净化， 然后用连续流动分析仪进行了六价铬的测定。结果 文中方法的检出限为0.044 mg/kg， 回收率在84.0%~99.0%之间， 相对标准偏差小于8.60%。结论 建立的方法具有操作简便、 快速、 灵敏度高等优点， 适用于纸质品中六价铬残留量的快速测定。 |
| 英文摘要: |
| The aim of this study was to develop a method for the determination of Cr(VI) residues in paper-made packaging by continuous flow method after solid phase extraction cleanup. Cr(VI) was extracted from the sample by oscillation using the solution of potassium hydrogen phosphate (pH=8.0), cleaned up by solid phase extraction of polyamide, and then determined by continuous flow method. The detection limit of Cr(VI) in the method was 0.044 mg/kg, the recovery was in the range of 84.0%~99.0%, and the relative standard deviation (RSD) was less than 8.60%. The real sample analysis showed that this simple, fast and accurate method could be used for the determination of the residues of Cr(VI) in paper-made packaging samples. |
