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.
In this paper, 8-hydroxyquinoline-5-sulfonic acid fiber filter paper was synthesized, which can be used as micro-column fillers enrichment of 10 trace elements and separation of high salt components in the sample. The separation and enrichment of trace components are carried out simultaneously, making them particularly suitable for the pretreatment of samples before atomic spectrometry.
