据有关文献报导,发射光谱法分析铀化合物中的微量杂质元素,在国内外,一般多采用载体蒸馏法、蒸发法和化学光谱法。前两种方法,六十年代在国内颇为盛行,现已满足不了生产要求,只有化学光谱法的研究仍在深入。该方法由于已将具有放射性的大量铀分离掉,既避免了放射性对人体的损害,又除去了大量铀线对分析线的干扰,降低了杂质元素的检出限。但是,化学光谱法,手续繁杂,误差较大;同时抗干扰能力较差。 ICP-AES法测定铀化合物中的微量杂质元素正可保持其优点克服其缺点。本方法, According to the literature, emission spectrometry analysis of uranium compounds in trace impurities, at home and abroad, the general use of carrier distillation, evaporation and chemical spectroscopy. The first two methods, the sixties in the country is quite prevalent, is now unable to meet the production requirements, only the study of chemical spectroscopy is still in-depth. Since this method has separated a large amount of radioactive uranium, it not only avoids radioactive damage to human body, but also removes a large amount of uranium interference to the analytical line and reduces the detection limit of impurity elements. However, chemical spectroscopy, procedures complicated, larger error; at the same time anti-interference ability is poor. Determination of Trace Impurities in Uranium Compounds by ICP-AES The advantages are maintained by overcoming its disadvantages. This method,
