| 摘 要： | 光学玻璃中的各种元素对玻璃的光学性能有不同的影响。如加入镉可以提高玻璃折射率;砷的引入能增加玻璃的透光度,含铅玻璃具有低成本、高折射性等优点。但是镉、砷、铅均为有毒元素,玻璃加工和处理过程以及毒废弃物的处理都可能引起水、土壤、大气的污染并给人体带来一定的危害 |

| Abstract: | 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. |
| Keywords: | Microwave digestion Optical glass Electrothermal evaporation atomic fluorescence Hydride generation atomic fluorescence Cadmium Arsenic Lead |
