Study on the Determination of 7×××Aluminium Alloy Elements by X-ray Fluorescence Spectrometer
Through orthogonal test of different experimental parameters such as current,voltage and counting time,the optimum test conditions of X-ray fluorescence spectrometry were determined.Standard aluminium alloy samples were selected and standard work-ing curves were established.The accurate determination of Si,Fe,Cu,Mn,Mg,Cr,Ni,Zn,Ti and Zr of 7××× aluminium alloy was realized.The precision of the method was investigated,and the relative standard deviation of each element in the aluminium alloy samples was lower than 0.7%.The standard samples were analyzed,and the measured values were in good agreement with the chemi-cal method,which could meet the needs of the accurate determination of each element in aluminum alloy.
