摘要
用HNO_3+HClO_4+HF混合酸分解冶金铁渣,用电感耦合等离子发射光谱法扫描测定铁渣中的铍,选择合适的波长,测定了分析结果的精密度、方法的检出限和回收率,加标回收率为94.0%~104.0%,结果表明,分析方法准确、可靠、简便,满足生产需要。
The metallurgical iron slag is decomposed with HNO_3＋ HClO_4＋ HF mixed acid. The suitable wavelength was selected by using inductively coupled plasma emission spectrometry. The precision of the analytical results,methods detection limit and recovery rate are all measured. The recovery rate was 94. 0% ~ 104. 0%. The results show that the analytical method is accurate,reliable and simple to meet the production needs.
