本文介绍了Ni—W合金中Fe、Co、Mn、Cu、Pb、Zn、Cd、Mg及Ca的原子吸收光谱分析法。用过氧化氢/硝酸溶解试样,以EDTA络合铁消除硅对铁的影响,硝酸锶为钙和镁的释放剂,在2％(V/V)的硝酸、15％(V/V)的过氧化氢混合介质中,连续测定上述九个元素,相对标准偏差均不大于2.5％。 This article describes the atomic absorption spectrometric analysis of Fe, Co, Mn, Cu, Pb, Zn, Cd, Mg and Ca in Ni-W alloys. The samples were dissolved with hydrogen peroxide / nitric acid to eliminate the effect of silicon on iron by EDTA-complexing iron. Strontium nitrate was a release agent for calcium and magnesium. The sample was treated with 2% (v / v) nitric acid, 15% Of hydrogen peroxide mixed media, continuous determination of the above nine elements, the relative standard deviation of not more than 2.5%.
