【Abstract】 The concentration of copper in high alumina zinc base alloy was determined by the method of flame atomic absorption spectrometry.By this method,there were no interferences from the matrix and other coexistent elements,and Cu in the range of mass fraction 2.0%—3.0% can be determined.The relative standard deviation of this method is 0.967%.The rate of recovery is 98.4%.更多还原
