摘　　要：镝铁合金中稀土总量的测定采用草酸盐重量法,以盐酸溶解,用过氧化氢氧化二价铁,在pH1.5~2.0条件下用草酸沉淀稀土分离铁,沉淀经高温灼烧后生成稀土氧化物,称量测定稀土总量。Oxalate gravimetic method was used to determine total content of rare earths in Dy-Fe alloy.Factors affecting the determination such as sample digestion,dogage of reative relagents,heat preservation time for samples and so on were investigated.The determined results are accurate and reliable.

关 键 词：镝铁合金 稀土总量 草酸盐重量法
