用337.1 nm 的氮分子激光诱导溶液中的氧化反应,从混合稀土中分离出了铈稀土。用感应耦合等离子体原子发射光谱术对反应产物中的铈、镧等元素含量作了测定,得出铈相对于镧的分离系数值为:β=11.5。
With 337.1 nm nitrogen laser induced oxidation solution, cerium rare earth separated from the mixed rare earth. The contents of cerium, lanthanum and other elements in the reaction product were determined by inductively coupled plasma atomic emission spectrometry, and the separation coefficient of cerium relative to lanthanum was obtained as follows: β = 11.5.
