摘要
Closed-vessel microwave-assisted digestion was utilized for the decomposition of hard-to-dissolve optical glass samples for the determination of the ultra trace amount of cadmium by electrothermal evaporation atomic fluorescence spectrometry（ETV-AFS）and arsenic and lead by hydride generation atomic fluorescence spectrometry（HG-AFS）.The limits of detection were found to be 0.08,0.1 and 0.7ngmL-1for cadmium,arsenic and lead,respectively.Relative standard deviation（RSD）was between 2%-5% which was adequate for trace analysis.The analytical results were in good agreement with those obtained by inductively coupled plasma mass spectroscopy（ICP-MS）for cadmium and inductively coupled plasma atomic emission spectrometry（ICP-AES）for arsenic and lead.
Closed-vessel microwave-assisted digestion was utilized for the decomposition of hard-to-dissolve optical glass samples for the determination of the ultra trace amount of cadmium by electrothermal evaporation atomic fluorescence spectrometry（ETV-AFS） and arsenic and lead by hydride generation atomic fluorescence spectrometry（HG-AFS）. The limits of detection were found to be 0. 08,0.1 and 0.7ngmL^-1 for cadmium, arsenic and lead, respectively. Relative standard deviation （RSD） was between 2% -5 % which was adequate for trace analysis. The analytical results were in good agreement with those obtained by inductively coupled plasma mass spectroscopy（ICP-MS） for cadmium and inductively coupled plasma atomic emission spectrometry （ICP-AES）for arsenic and lead.
