Abstract：This study established an ICP-MS(Inductively Coupled Plasma Mass Spectrometry)method for the determination of 10 trace impurity elements(calcium,magnesium,aluminum,iron,cobalt,nickel,copper,zinc,arsenic,and lead)in high-purity germanium dioxide.By optimizing sample pretreatment conditions and instrument working parameters,matrix effects and polyatomic ion interferences were effectively eliminated.The results showed that the method exhibited a wide linear range for all 10 elements,with correlation coefficients greater than 0.999.The detection limits ranged from 1 to 10 ng/g,spike recoveries were between 85%and 115%,and the relative standard deviations(RSD)were less than 10%.This method is simple,rapid,accurate,and suitable for the determination of trace impurities in high-purity germanium dioxide.
