稀土化学的研究虽有一百五十多年的历史,但由于稀土是一族化学性质很相似的元素,早期大量的时间都集中在分离单一稀土的研究上,直到1947年使用离子交换解决了单一稀土的分离后才使稀土化学的研究真正开展起来,距今也只不过卅多年的历史,因此稀土化学还 Although the study of rare earth chemistry has a history of more than 150 years, since rare earths are a family of elements with very similar chemical properties, a large amount of time in the early days was concentrated on the study of the separation of single rare earths until the single Only after the separation of rare earth chemical research of rare earth to carry out, dating back only years of history, so rare earth chemical
