摘要
本文利用高频电感耦合等离子体光谱仪直接测定铝合金中的Fe,Zn ,Mg ,Mn ,Ti,Cr和Cu杂质元素。选择了合适的实验条件 ,采用背景扣除法进行校正。方法简便 ,快速 ,可靠 ,具有良好的精密度和准确度。相对标准偏差为 1 7%～ 6 3 % ,回收率为 94 %～ 10 5 %。
A method for the determination of Cr, Zn, Fe, Mn, Ti, Cu and Mg impurity elements of alloy aluminum of ICP-AES was studied. Working conditions were optimized. The method is simple, rapid, precise and convenient. The relative standard deviation is less than 6.3%. The recovery is 94% -105%. The results are satisfactory.
