报道了P507萃淋树脂分离镨钕的双峰现象及其原因,料液中加入(CH_2)_6N_4可有效地消除双峰现象,且镨钕分离的最佳温度为～40℃。
The phenomenon of bimodal separation of praseodymium and neodymium by P507 extraction resin and its reason were reported. The addition of (CH_2) _6N_4 to the feed solution could effectively eliminate the bimodal phenomenon, and the optimum temperature for the separation of praseodymium and neodymium was ~ 40 ℃.
