摘要
本文在以氮气为载气的条件下,用1:2盐酸分解样品,进行二氧化碳,亚铁和全铁的连续测定。用原子吸收光谱在一份试液中测定杂质元素。20mg试样完成菱铁矿八个主次元素的分析,操作简便,结果较为满意。
A rapid and simple micro scheme was devised in which, a weighing portion of 15 mg was decomposed under protection of nitrogen, C032-, Fe2+ and Fe3+ were determined chemically. Another Sample Portion(5mg)was analyzed for K, Na, Ca, Mg and Mn by AAS.The results Were Satisfactory,
