本文提出了一个十分快速、简便的同时分光光度测定黄铜矿单矿物中铜和铁的新方法。方法以EDTA为显色剂,通过对测量波长的选择,实现了铜和铁与EDTA配合物的光谱吸收在完全互不干扰的情况下进行测量。由于省去了通常采用的氨水沉淀分离铜、铁这一步骤,一次显色即可同时测出铜和铁的分析结果,大大地简化了分析手续,提高了工作效率。 (一) 实验部分
This paper presents a very rapid and simple method for simultaneous spectrophotometric determination of copper and iron in chalcopyrite mono-mineral. Methods With EDTA as the chromogenic reagent, the spectral absorption of Cu, Fe and EDTA complexes was measured without any interference with each other through the choice of measurement wavelength. As the elimination of the commonly used ammonia precipitation separation of copper and iron this step, a color can be measured at the same time, the results of the analysis of copper and iron, greatly simplifying the analysis procedures and improve work efficiency.
