摘要
本文提出了痕量铅的在线流动注射离子交换预浓集火焰原子吸收测定方法，并将其应用于天然水的分析．文中讨论了不同缓冲溶液、ｐＨ值、富集时间、离子交换树脂对富集效果的影响．
In this paper,a flow-injection system with on-line ion-exchange preconcentration and atomic absorption detection was developed and applied to the determination of tEe amount of lead in natural water.The effects of different buffer solutions PH the time of preconcentration and ionexchange resins on concentration efficiency were discussed.
