原子吸收分光光度法测定矿石中的微量铬,一般采用空气-乙炔焰。但在此火焰中,干扰元素较多。资料中曾报导过克服干扰的各种释放剂,但不十分理想。资料提出以Na_2SO_4-BeSO_4混合剂作为释放剂,但铍引入火焰,对人体有害。因此进一步研究这些干扰有一定实际意义。本报告研究在氧屏蔽空气-乙炔焰中原子吸收分光光度法测定矿石中微量铬的条件。试验了硅酸盐岩石和铁矿中共存元
Atomic Absorption Spectrophotometric Determination of trace chromium in the ore, the general use of air - acetylene flame. But in this flame, there are more disturbing elements. It has been reported in the data that various release agents that overcome interference are not very satisfactory. The data suggest Na_2SO_4-BeSO_4 as a release agent, but beryllium is introduced into the flame and harmful to the human body. Therefore, further study of these disturbances has some practical significance. This report investigates the conditions for the determination of trace chromium in ores by atomic absorption spectrophotometry with oxygen-shielded air-acetylene flame. Test coexisting elements in silicate rock and iron ore
