摘　　要：本文利用原子吸收光谱仪配套的独特的操作软件,实现了水样品在石墨管中的预富集,从而使超痕量铊的直接测定成为可能.该方法与标准方法对比,具有流程简单、用时大大缩短、灵敏度高、重现性好、准确性高等优势.Ultra-trace level of thallium was detected with an accurate and reliable on-line enrichment-graphite furnace atomic absorption spectrum method. Comparing to standard methods,this method is more user-friendly,convenient,fast and accurate. It meets many global regulations for water quality control on ultra-trace level thallium detected in drinking,surface,and waste water.
