Abstract采用硝酸和氢氟酸溶解样品,高氯酸冒烟赶氟避免生成氟化稀土沉淀,选择La333.749nm、Ce 456.236nm、Pr 417.939nm、Nd 406.109nm及Y 371.030nm作为分析线,扣除背景点消除基体干扰,运用干扰系数法克服谱线间干扰,通过基体匹配法配制标准溶液系列消除基体效应的影响,使用电感耦合等离子体原子发射光谱法(ICP-AES)测定铝硅活塞合金中镧、铈、镨、钕和钇。结果表明:镧、铈的测定范围在0.01%~2.00%,镨、钕、钇的测定范围在0.005%~2.00%,校准曲线线性相关系数不小于0.999 8。方法中各元素检出限为0.000 3%~0.001 8%。实验方法用于测定稀土铝合金合成试样中镧、铈、镨、钕和钇,结果的相对标准偏差(RSD,n=6)在0.50%~2.4%之间,加标回收率在94%~105%之间。实验方法用于含有稀土的铝合金标准样品中镧、铈、镨、钕和钇的测定,结果与电感耦合等离子体质谱法(ICP-MS)测定值相吻合,测定的稀土总量RE与认定值也相吻合。
