天然水中重金属离子的原子吸收测定

The Determination of Heavy Metal Ions in Natural Waters

本文采用了在线流动注射离子交换预浓集原子吸收法,对天然水中的重金属离子进行了测定;讨论了不同缓冲溶液、pH值、富集时间和离子交换树脂对富集效果的影响。并对天然水中的Cd、Mn、Cu、zn的含量进行了测定,取得了满意的结果。

in this paper the method determination of heavy metalions in natural waters by Atomic Absorption Spectrometry in flow injection system with on—line ion—exchange Preconeentration was developecl. The effects of different buffer solutions pH the time of preeoncentration and ion—exchange resions on the concentration efficiency were also discussed The Cd Mn、Cu、Zn in natural waters have been determined with satisfactory results。
