| 摘 要： | 比较五种石墨管对锑的干扰的影响,实验结果表明:石墨管中引入微管或平台后,由于具有好的空间等温性,可明显地抑制外来离子对锑的干扰;而石墨管热解涂层对抑制锑干扰有显著影响。镍的干扰在使用双管(1)时虽得到抑制,但仍无法消除。实验表明:采用Mo+W难熔碳化物涂层处理,并加入EDTA及峰面积测定方式可消除镍对锑的干扰。

| Abstract: | The influence to the interferences on determination of Sb using five kinds of graphite tubes is reported. The introduction of microtube or platform, for its more homogeneous temperature, can increase the sensitivity and inhibits the interferences of foreign ions. The interference of nicle, which can not be eliminated with tube-in-tube technique, can be eliminated by the addition of EDTA; coating of Mo and W carbides and measurement of peak area. |
