Determination of Sixteen Elements in Al-Ti-B Alloys by ICP-AES

Jiang Su

Abstract

The amounts of sixteen elements(Ti,B,Fe,Si,Ga,Cu,Sr,Zr,Zn,Mn,Mg,Ni,Pb,V,Cd and Cr) in Al-Ti-B alloys were determined simultaneously by ICP-AES.The analytical lines,matrix effect of aluminum and the pretreatment were studied.The relative standard deviation and the recovery of the method were in the range of 0.4%—3.0%(n=6),95%—110%,respectively.The method is accurate and simple with satisfactory precision and accuracy,and is suitable for routine control analysis.
