摘要
少铕氯化稀土溶液用碳酸氢铵沉淀，沉淀物经５００℃的烧１ｈ，铈的氧化率大于９９％，稀硫酸浸出后渣率小于１％。
The reaction of solution of rare earth chloride containing a low amount euripium with bicarbonate of ammonia leads to precipitation.The precipitation is calcinated at 500℃ for an hour.The ratio of oxidation of cerium(Ⅲ) is more than 99%.The calcinated product is leached in dilute sulphate acid.The residue ratio is less than 1%.
