强酸型离子交换纤维富集-火焰原子吸收测定水中痕量铜、铅、镉、镍
Determination of trace copper,lead,cadmium and nickel in water by enriching with the new cation exchange fibers column—flame atomic absorption spectrometry
【摘要】 通过强酸型离子交换纤维柱,在同一水样中同时富集和洗脱了铜、铅、镉、镍,采用火焰原子吸收光谱法测定,并对富集条件及洗脱条件、干扰因素进行了探讨。该方法简便易行,回收率在96.1%~105.5%之间,测定的相对标准偏差小于5.0%。
【Abstract】 The simultaneously determination of trace copper,lead,cadmium and nickel in water after separating and enriching with the new cation exchange fiber By FAAS is described in this paper.The enriching and eluting conditions were studied.The interference for common existing metal ions was discussed.The recovery of four metal ions in same solution is 96.1%～105.5%,RSD is less than 5.0%.The characteristics of this method is fast,simple and convenient.
