流动注射分析(FIA)有设备简单、操作方便、速度快、成本低、精度高等特点,是一种湿化学自动分析技术。已在农业和环境等许多分析领域广泛应用,受到分析工作者的极大重视。1982年以来,日本学者陆续发表了硅酸盐岩石中铁、铝、硅、磷、钛、钙等元素的流动注射分析方法。其中铁铝的测定本刊已于1983 Flow injection analysis (FIA) has the characteristics of simple equipment, convenient operation, high speed, low cost and high precision. It is a kind of wet chemical automatic analysis technology. Has been widely used in many fields of analysis, such as agriculture and the environment, and is highly regarded by analysts. Since 1982, Japanese scholars have successively published the flow injection analysis methods of elements such as iron, aluminum, silicon, phosphorus, titanium and calcium in silicate rock. One of the determination of iron and aluminum has been published in 1983
