摘要
采用断续流动氢化物发生无色散原子荧光分析法同时测定水中的微量砷、硒,确定了仪器及氢化物产生的最佳实验条件.测定结果表明实际样品中砷的回收率在85%～110%之间;硒的回收率在92%～102%之间,样品测量值的相对标准偏差砷在1.1%～4.8%之间,硒在5.0%～5.9%之间.本方法可一次消化样品并同时测定砷、硒的含量,具有操作简单、快速、基体干扰少、灵敏度高、分析结果稳定可靠、节省试剂等特点,并且采用自动进样,适于大量样品的快速分析.
A method of intermittently flowing hydride generation non-dispersive atomic fluorecence spectrometry was used to analyze trace amounts of arsenic and selenium in water under optimized working conditions. The recovery rates of analyzed arsenic and selenium with trace amounts in water range from 85% - 110% and 92% - 102%, respectively, and relative standard deviations are between 1.1% - 4.8% and 5.0% -5.9%, respectively. The method used in it is simple, quick, highly sensitive and broad in a large liner range. Due to tanks to auto-injection, it is applicable to rapidly analyze a large quantity of aqueous samples.
