我国为氧化铝的生产大国,在氧化铝的生产同时也就伴随着排放大量的赤泥,而在国内外现在赤泥的有效利用仍然没有大规模的高效方法。大量的赤泥的产生已经对我们赖以生活的土地、环境等造成了严重的污染。通过对赤泥中稀有元素的测定,可以指导相关的赤泥中稀有元素的总量进行初步的判断,并对其下一步的利用等分析也是非常重要的手段。本文主要论述了在电感耦合等离子体原子发射光谱法下对赤泥浸出液中的稀土元素进行测定的方法及过程,且通过其他方法的测定进行了对比,得出了本方法测定及结果的可靠性。
China is a major producer of alumina. Alumina production is accompanied by a large amount of red mud emissions. However, there is still no large-scale and efficient method for the effective utilization of red mud at home and abroad. A large amount of red mud has caused serious pollution to the land and environment on which we live. The determination of rare earth elements in red mud can guide the preliminary determination of the total amount of rare elements in the red mud and analyze its utilization in the next step. In this paper, the method and process of determination of rare earth elements in red mud leachate by inductively coupled plasma atomic emission spectrometry are discussed, and compared with the determination of other methods, the reliability of the method and the results obtained .
