氢化物发生-电感耦合等离子体原子发射光谱法同时测定锑锭中氢化物元素和非氢化物元素

运用改进的同心喇叭口双溶液管雾化器，采用连续氢化物发生法，在酸性介质中，对锑锭样品溶液既发生雾化作用，又对可形成氢化物的元素（Ａｓ、Ｓｅ、Ｐｂ）发生氢化作用，使它们的发射强度得到显著提高，而对非形成氢化物的元素（Ｆｅ、Ｃｕ）的发射强度基本不受影响，利用ＩＣＰ－ＡＥＳ同时测定锑锭中形成氢化物的元素和非形成氢化物的元素。对实际样品进行对比检测，结果令人满意。

Simultaneous Determination of Hydride Forming and Non -Hydride Forming Elements in Ingot Antimony by Hydride Generation -Inductively Coupled Plasma -Atomic Emission Spectrometry

A simple and compact concentric glass nebulizer-hydride generator system with two entrances for sample solution and sodium borohydride solution has been developed. The system for simultaneous determination of both hydride forming and non-hydride forming elements in ingot antimony has also been successful. This system is no larger than a conventional nebulization system and can be easily fitted into the nebulization compartment of the spectrometer. No extra gas-liquid phase separator is needed, and with this system, the emission intensity for the hydride forming elements can be improved, while that of the non- hydride forming elements remains practically unaffected. The method has been applied to the analysis of actual samples with satisfactory results.
