Abstract：To ensure the purity during thealuminum aloy alloying process，it is necessary tocontrol the impurity contentinprimaryallyingots.Thecontentsofsilicon，iron，copper，aluminum，manganese，andnickelimpuritiesin primary magnesium ingotsare determined using Inductively Coupled Plasma Atomic Emision Spectrometry （ICP-AES） andX-Ray Fluorescence spectrometry （XRF）.For ICP-AES，samplesare dissolvedwith hydrogen peroxidehydrochloricacid，andthespectral linesareoptimizedalong withthematrix-matching method，achievingadetection limitof 0.000 01%～0.00027%，a spike recovery rate of 92%～102% ，anda repeatabilityRSD of <2.3% . For XRF， the optimal analysis conditions are determined，with a detection range of 0.000 1% ～0.100 O%and arepeatabilityRSD of ⩽ 3.1% .Theresultsindicate thatboth methodsexhibit goodaccuracyandrepeatability，withICP-AESofering higher sensitivity， while XRF is more suitable for rapid and non-destructive testing.
