Abstract

A method of determination of Mo,Cr,Sn,Zr,Cu and B in TB6titanium alloy by inductively coupled plasma atomic emission spectrometry(ICP-AES)was established.The sample was decomposed with hydrochloric,hydrofucoric and nitric acid,the interference from main co-existing elements were studied to choose the analytical lines.The experiment of selection of analysis lines were:Mo 202.031nm, Cr267.716nm,Sn 189.927nm,Zr 343.823nm,Cu 324.754nm,B 249.772nm.The matrix effect was corrected by matrix matching.The determination results are in good agreement with standard reference materials.The recovery rate is from 90to 106%,the RSD is less than 2%.
