摘要
采用碳酸钠-碳酸钾-硼酸分解试样,盐酸浸取,电感耦合等离子体原子发射光谱法测定粉煤灰中的铝含量。铝的测定范围5.00%~25.00%。经加标回收实验,铝元素的加标回收率为99.6%~106%(n=3),方法准确简单,适用于粉煤灰中铝的测定。
The sample was decomposed with sodium carbonate-potassium carbonate-boric acid,leached with hydrochloric acid,and the content of aluminum in fly ash was determined by inductively coupled plasma atomic emission spectrometry.Measuring range of Al is 5.00%to 25.00%.After the standard recovery experiment,the recovery rate of aluminum element is 99.6%—106%(n=3).The method is accurate and simple,and is suitable for the determination of aluminum in fly ash.
