| Abstract: | The method of determination of cadmium content in new aluminum alloy by ICP-AES was developed. The sample was dissolved by HCl-HNO3. Interferences were eliminated by using the matrix matching method and the proper analysis spectral lines were selected. The working parameters were optimized. The relative standard deviation of determination results was 0.15%（n=10） and the recovery was 96.6%-100.5%. The proposed method is simple,rapid, accurate and suitable for determination of cadmium content in aluminum alloy. |
