| 摘 要： | 本文研究了黄原酯棉富集铅的条件，探讨了应用石英缝管技术测定铅的方法。实验表明ｐＨ＝７左右时，黄原酯棉能够定量地富集水中痕量铅，以１％ＨＮＯ３、水浴２０ｍｉｎ即可定量解脱。应用石英缝管技术可比常规火焰测定铅的灵敏度提高３．３倍。本方法可应用于野外富集。

| Abstract: | A method for determination of trace lead in water by FAAS with slotted quartz tube after separation and enrichment with cotton cellulose xanthate is developed.The lead is enriched quantitatively when pH =7 and liberated quantitatively with boiling-1% nitrate acid.The sensitivity of this method is 3.3 times than that of conventional FAAS. |
