摘要
本法研究了硝酸镧作为释放剂消除铝等元素对镁的化学干扰,探讨了空气-乙炔火焰原子吸收光谱法测定镁的最佳条件,在最灵敏吸收波长处测定催化剂中的镁含量,并进行了样品对照和加标回收试验。该法操作简便、快速、重复性好、数据可靠,结果均令人满意。
The amount of magnesium in reforming catalyst was determined by atomic absorption spectrometry with lanthanum nitrate as releasing reagent. The operating conditions were optimized. The relative standard deviation is 0. 5%-2. 2%. The recovery is 98%-103%, This method is simple ,rapid and accurate.
