摘要
本文以铬天青S作显色剂,对流动注射-分光光度法测定硅酸盐岩石中的铝作了详细的研究。它较已报导的流动注射分析测定铝的方法有更好的线性范围(0～10ppmAl)和精密度(相对标准偏差为0.45％),测定速度达到200样/小时。将该方法用于测定地矿部一级岩石标准参考样品中的铝,分析结果与标准参考值相吻合。
A method for the spectrophotometric determination of aluminium in silicate rocks by flow injection has been studied in details. The dynamic linear concentration range was 0-10ppm of Al, and the relative standard deviation of the determination was 0.45%. High throughput of the flow system of 200 sam-ples/h was achieved.
