| 摘 要： | 本文合成了8-羟基喹啉-5-磺酸纤维滤纸片,以此做为微柱填充物同时富集了10种痕量元素,并分离了样品中的高盐组分.本方法可使痕量组分的分离与富集同步进行,因而特别适用于原子光谱测定前样品的预处理.

| Abstract: | Oxine cellulose was prepared with 8-hydroxyquinoline-5-sulfonic acid covalently bound to filter flakes. Ten elements were preconcentrated on microcolumn filled with the cellulose and analyzed by inductively coupled plasma atomic emission spectrometry after being etuted with dilute nitric acid. At given pH-value, alkali and alkaline earth metal ions can be quantitatively separated as matrix elements. The usefulness of the method was shown by the results of the analysis of certified reference materials. |
