摘要
使用多道石墨炉原子吸收仪,采用石墨管涂层处理技术,在对几种基体改进剂的改进作用进行实验比较的基础上,选择1%ZrOCl2为基体改进剂,对水中的Cu、Pb、Zn、Cd4种元素进行了同时测定,并应用此方法对北京化工二厂和京密引水渠的水样进行了加标回收试验,取得了较为满意的结果。
With multi-channel AAS and coating technology for graphite tube, four elements Cu,Pb,Zn and Cd in water are determined simultaneously with matrix modifier 1% ZrOCl_2,one from the comparison of several modifiers. The recovery tests of the method applied to the samples from Beijing Number 2 Chemicals Plant and Jingmi diversion canal are satisfactory.
