包头冶金研究所用P507萃淋树脂制取了高纯氧化铕。该法用90%粗Eu_2O_3为原料,通过一次淋洗分离制取了≥99.95%～99.99%Eu_2O_3,收率为86.4%,≤99.95%～99.9%Eu_2O_3收率为5.6%。这是应用萃淋树脂在稀土分离工艺上的新进展,是目前制取高纯稀土元素较好的分离方法之一。该工艺采用廉价的盐酸淋洗稀土比较EDTA为淋洗剂的离子交换法和锌粉还原—碱度法制取高纯 Baotou Metallurgy Institute made P507 extraction resin made of high purity europium oxide. The method uses 90% coarse Eu 2 O 3 as the raw material and prepares 99.95% ~ 99.99% Eu_2O_3 with a yield of 86.4% and a yield of 99.95% ~ 99.9% Eu_2O_3 by 5.6%. This is the application of extraction resin rare earth separation process on the new progress is the current preparation of high purity rare earth element one of the better separation methods. The process uses low-cost hydrochloric acid leaching of rare earth ion exchange EDTA compared to eluent and zinc reduction - alkalinity method of high purity
