- 中文摘要: The quantitative analysis of iron and cobalt in super alloys has been studied. 1,10-Phenanthroline and nitroso-R salt provide the chromophores for iron(II) and cobalt(II), respectively. The possibility of applying these photometric methods to a relatively complex substance, such as a super alloy, has been evaluated on the bases of precision and accuracy. The absorbance characteristics of metal complexes and the possible interference from foreign ions have also been carefully investigated. The presence of a high concentration of Ni results in a reducation of the amount of 1,10- phenanthroline available for the formation of ferroin complexes while Mo does not have this effect. The analytical methods have been applied to the super alloys, Inconel 718, Hastelloy X, and Inconel X-750. The modified 1,10- phenanthroline photometric method and the standard nitroso-R salt photometric method give high accuracy and good precision. This illustrates the analytical applicability of these reagents to super alloys.
