【摘要】 <正> 1978年,我们首先提出了氢氧化铝-蛤蜊壳粉-氯化钾复合富集剂的制备和富集铀的报告。本文就这种富集剂沉淀终点溶液的PH、沉淀时溶液溫度、沉淀放置(陈化)时间、烘干溫度、硫酸铝浓度、氨水浓度及蛤蜊壳粉含量等条件对富集铀的影响进行了实验。更多还原

【Abstract】 Test results showed that the enrichment of uranium was closely ralated to the preparation conditions of hydroxide aluminium-clam shell powder-potassium chloride composite agent-enriched. An optimum condition of the preparation of hydroxide aluminium-clam shell powder-potassium chloride composite agent-enriched is suggested in this paper.更多还原
