With the development of nulear power industry , more and more attention has been given to the spent nulear fuel reprocessing . purex process will remain predominant in the foreseenable future . because the valence of np , one kind of transuranium elements , is easy to interchange , the route of np in purex process is difficult to be controled . a lot of work has been done on the control of neptunium way in the world 隨著核電的發展,乏燃料后處理引起了人們的廣泛關注。 purex流程在乏燃料后處理中一直占有主導地位。由于超鈾元素np的化學價態容易相互轉變,使purex流程中np的走向不易控制而傾于分散。
