火焰原子吸收法测定醋酸反应液中铑含量

Determination of Rhodium in Acetic Acid Reaction Solution by Flame Atomic Absorption Spectrometry

采用火焰原子吸收法,铑元素空心阴极灯,以乙炔-空气为燃气,在343.5 nm特征谱线波长处测定醋酸反应釜液中铑元素的含量。试样经硫酸和次氯酸钠处理后,可有效消除其他杂质元素的干扰。实验过程简单、快速、准确,能及时为工艺调整提供参考。

In this paper,Rhodium in acetic acid reactor solution was determined by flame atomic absorption spectrometry with Rhodium hollow cathode lamp and acetylene-air as fuel gas at the wavelength of 343.5 nm.The sample was treated with sulfuric acid and sodium hypochlorite,the invention can effectively eliminate the interference of other impurity elements,and the experimental process is simple,fast and accurate.It can provide reference for process adjustment in time.
