| Abstract: | A method for the determination of Cu,Ni,and Zr in Ti-based alloy by ICP-AES is proposed.The optimum measurement conditions were selected experimentally.The sample dissolution methods,the acidity,the selection of the internal standard elements and their amounts,and the influences of matrix and coexisting elements were studied.The method is accurate and precise.The recoveries were 97%~102%,and the RSDs were less than 2%. |
