| 摘 要： | 建立了硝酸压力溶弹溶样、石墨炉原子吸收法测定硫磺中砷、硒、碲元素的方法。通过正交试验确定样品的溶解条件,选择适当的基体改进剂和最佳的石墨炉升温程序,一次溶样即可实现砷、硒、碲三种元素的检测。该法的回收率为90．0％～110．0％,测定结果的相对标准偏差为2．5％～4．8％。

| Abstract: | A new method was set up to determine the arsenic, selenium and tellurium in sulphur by the graphite fumaee a-tomic absorption spectrometry by means of the sample being solved with HNO3 in the pressure vessel. The factors affecting the solving result have been analyzed by orthogonal experiment. The proper matrix improver and the best temperature increasing the procedure of the graphite furnace have also been determined. The solution obtained can be used to determine arsenic, selenium and tellurium, respectively. The recovery of the method is 90. 0% ~ 110. 0% and the RSD is 2. 5% ~4. 8% . |
