The sample was dissolved with hydrochloric acid,nitric acid,hydrofluoric acid and perchloric acid. By optimization,the analytical spectral lines without interference have been selected. Chromium,zirconium,nickel and iron in copper-chromium-zirconium alloy were determined by inductively coupled plasma atomic emission spectrometry( ICP-AES) with the copper matrix matching method. The real sample was analyzed by the method with the relative standard deviation( RSD) calculated lower than 4. 4%,and recoveries of...
