各种冶金物料(诸如:含有大量铜、铁、铅、铝、硅、钙和镁的矿物,精矿和尾矿)中一般钴、镍和锰的含量在1×10~(-3)％以上,尽管如此,为了便于用原子吸收法测定钴、镍和锰,避免溶液高酸度和基体干扰,仍需适当采用萃取方法,或者标准加入法。波兰华沙工业大学化学系两位分析化学家提出,采用两种 The contents of cobalt, nickel and manganese in various metallurgical materials (such as minerals, concentrates and tailings containing large amounts of copper, iron, lead, aluminum, silicon, calcium and magnesium) are in the range of 1 × 10 -3% However, in order to facilitate the determination of cobalt, nickel and manganese by atomic absorption spectrometry, the high acidity and the matrix interference of the solution should be avoided, and the extraction method or the standard addition method is still appropriate. Two analytical chemists at the Department of Chemistry at the Warsaw University of Technology in Poland proposed using two
