稀土硅铁合金中稀土总量的分析

Analysis of Total Rare Earth in Rare earth-Silicon-ferroalloy

利用在pH=2.8时,稀土离子与草酸形成草酸稀土沉淀的原理,用草酸稀土重量法测定稀土总量,取得了较好的效果。

Using the principle of ions of rare earth and oxalic acid forming oxalic acid-rare earth deposition, the oxalic acid-rare earth weight method is used to determine total rare earth, obtaining better results.
