| Abstract: | A new method was proposed to preconcentrate and separate trace rare earth elements bysolid-liquid extraction with microcrystamne naphthalene. Sc and other rare earth elements canbe precipitated by oxine in the range of PH 4. 5 ~ 8. 6 and PH 7. 2 ~ 8. 6 respetively. The oxinate may be extracted by microcrystalline naphthalene quantitatively under certain conditions.The effects of various experimental Parameters are optimized. |
