【Abstract】 The conditions for determination of Si in Cooper-alloy by ICP-AES were studied. Interference of base solution can be despeled by standard add. Under the optimum condition, the recoceries of the method is 98.7%～102.3%, 0.001%～0.5% Si can be measured. The method has high good accuracy. (Si in Copper-alloy was measured for 10 times, RSD≤0.022 1). The results are satisfactory.更多还原
