| 摘 要： | 采用平台石墨炉原子吸收光谱法测定了碘化铯晶体中铊。研究了碘化铯对钯－硝酸镁基本改进剂中铊吸光度影响，用预混合钯－硝酸镁和样品溶液，由于在碘化物溶液中易析出金属钯而使测定结果降低。用样品溶液和基体改进剂分别加入到石墨炉中的标准加入法可得到满意的结果。

| Abstract: | he determination of thallium in cesium iodide crystal by platform graphite furnace atomic absorption spectrometry has been studied.The effect of cesium iodide on thallium atomic absorbance in the presence of palladiummagnesium nitrate as a matrix modifier was investigated .The results obtained by premixing palladiummagnesium with the sample solution were lower than those by standard addition method due to the precipitation of metallic palladium in the iodide solution.Satisfactory results can be obtained by adding the sample solution and matrix modifier separately into the graphite furnace. |
