摘要
本文用探针原子化-石墨炉原子吸收技术直接测定地质材料中的镓。与管壁原子化法相比,本法有较高的灵敏度和较低的检出限,基体影响大大降低。本法不用灰化阶段,简单快速,对6个一级岩石标准样品进行分析,测定结果与推荐值符合,加标准试验回收率满意。
The figures of merit of probe atoinisation for GF AAS as a practical trace element analysis approach has been investigated. Experimental results showed that interference effects which were observed in tube wall atomization disapoeared when using probe atomization instead. Six national standard reference rock samples were analysed in order to assess the applicability of this techniqne in real sample analysis, and the results were in good agreement with the certified values.
