研究了 EDTA容量法测定镝铁合金中稀土总量.采用氟化分离消除铁对滴定的干扰.进行了加料回收和精密度实验,回收率在 99%~101%之间,RSD<1%,被分析元素的测定范围在70%~90%.对容量法测定镝铁合金中稀土总量的研究结果令人满意.
研究瞭 EDTA容量法測定鏑鐵閤金中稀土總量.採用氟化分離消除鐵對滴定的榦擾.進行瞭加料迴收和精密度實驗,迴收率在 99%~101%之間,RSD<1%,被分析元素的測定範圍在70%~90%.對容量法測定鏑鐵閤金中稀土總量的研究結果令人滿意.

EDTA volume method was used to determine total rare earth contents in Dy-Fe alloy.Iron interference was eliminated by the addition of fluoride ions.Recovery in 99%~101% and RSD less than 1% were obtained.This method is accurate.
