摘要
介绍了用电感耦合等离子体原子发射光谱法测定钕铁硼合金中硼、铝的方法。研究了基体和共存元素对被分析元素的光谱干扰。采用基体匹配法克服基体效应影响,利用仪器软件建立数学模型消除主量元素的光谱干扰。进行了回收率,精密度和准确度试验。RSD<2%,回收率98%～103%。结果表明,本方法快速、准确,可以满足钕铁硼合金中硼、铝的测定要求。
B and Al in Nd-Fe-B alloy were determined simultaneously by inductively coupled plasma-atomic emission spectrometry. The effects of matrix and coexistent elements on the determination were studied. The effect of background was corrected by matrix match and the interferences of matrix and principal ele- ments on spectra were elminated by establishing mathematical model with the software of the instrument. The recovery, precision and accuracy were tested. The recovery was 98%～103% and RSD was 〈2%. The results showed that the method was rapid and accurate.
