摘要
本文用导数光度法同时测定样品中的铁和镍,并对铁、镍络合物二组分的导数光谱性质和测定条件进行了研究,选出其最佳条件,解决了互相干扰问题,进而提出一级导数光度法同时测定铁和镍的新方法。该法简便、快速、用于铝合金样品分析,获得满意的结果。
In this report, a new simultaneous determination method for iron and nickel by derivative spectrophotometry was presented, and the derivative spectrophotometric properties of iron and nickel complex with 5-Br-PADAP were investigated. The proposed method was simple, rapid to operate and with satisfactory results.
