本文介绍一种新的小型氢化物发生器,它适用于发生氢化物-火焰原子吸收测定砷、硒、碲、锑、铋、锡等元素。测定灵敏度比常规溶液直接喷雾火焰原子吸收法提高至19～78倍,检出限也有所改善,精密度与常规火焰法相当。该发生器具有灵敏度高、结构简单、操作方便、不需要特殊设备及专门技术等特点。初步研究了其使用性能及测定条件。 This article describes a new small hydride generator that is suitable for the determination of arsenic, selenium, tellurium, antimony, bismuth, tin and other elements by hydride generation - flame atomic absorption spectrometry. The determination sensitivity is 19 ~ 78 times higher than that of direct spray flame atomic absorption spectrometry. The detection limit is also improved. The precision is the same as the conventional flame method. The generator has high sensitivity, simple structure, easy operation, does not require special equipment and expertise and so on. Preliminary study of its performance and determination of conditions.
