摘要
介绍了原子吸收法使用富燃性空气-乙炔火焰测定钢中钼的测定条件及各种酸的影响和相关共存元素的干扰试验,试验得到在盐酸、硝酸、高氯酸、磷酸、硫酸中,硫酸对测定有较大影响,应避免使用硫酸;在铁、锰、钨、铬、铅共存元素中,铬、铅对钼的测定影响小。试验提出加入磷酸为释放剂的消除方法。本方法具有简便、快速的优点。
The conditions for in-steel molybdenum testing using very flammable air-acetylene flame by atom absorption method, the effect of various acids and the interference test results of correlated intergrowth elements are described. It is concluded from the tests, of various acids, such as hydrochloric acid nitric acid,hyperchloric acid, plosphoric acid, and sulfuric acid, sulfuric acid has the greater effect on the testing and should be avoid. In the intergrowth elements of iron, manganese, tungsten, chromium and lead, the latter two have little effect on molybdenum testing. It is proposed to use phosphoric acid as the releasing agent to eliminate the interference. This method has the advantages of simplicity and rapidity.
