Abstract
The ICP-AES method for the determination of Ge in GdSiGe series alloys was studied. As the three main elements in the alloys, Gd, Si, and Ge differ greatly from each other in chemical properties, it was difficult to pretreat the sample. Two decomposition methods were compared, and a mixture of HNO3 + HF was used to decompose the sample and the effect of the HF amount on the sample decomposition was examined. The adsorption effect of GdF3 on Ge was discussed. Three GdSiGe series alloy samples were analyzed, and the RSDs of this method were in the range of 0.85% ∼ 2.66%.
