紫外及导数吸收光谱法直接测定钕铁合金中铁和谱、钕
摘要:
钕铁合金是用于制备Nd-Fe-B永磁体的材料,在它的生产中需要测定铁和镨、钕,迄今尚未见有简便分析方法的报导。常规吸收光谱法测定镨、钕的灵敏度低、对低含量镨更难满足要求,笔者之一曾用稀土高氯酸溶液的三阶导数光谱法测定了镨钐钴合金及钇铝石榴石等样品中大量或少量单一稀土元素,取得了满意的结果[1,2]。

DIRECT DETERMINATION OF IRON,PRASEODYMIUM AND NEODYMIUM IN NEODYMIUM-IRON ALLOY BY UV SPECTROSCOPY AND THE THIRD ORDER DERIVATIVE SPECTROPHOTOMETRY
Abstract:
A new method for the analysis of neodymium-iron alloy is described. The sample is dissolved in HCLO4. Neodymium and praseodymium are determined by the third order derivative spectrophotometry, iron by UV spectroscopy. The method is simple, rapid and accurate.
