中文摘要: |
文章较为系统地研究了铼-锇定年法中丙酮萃取铼的实验条件,对萃取介质的碱度和萃取剂的用量进行了优化,并对振荡萃取时间以及碱洗进行了选择。优化后的实验条件对铼有较高的回收率,对其他杂质元素也有较高的分离系数,不仅简化了实验流程,而且节约了化学试剂。 |
英文摘要: |
The enperimental condition for rhenium extraction with acetone was studied comprehensively. The effect of amount of extracting reagent, alkalinity of the system, the extracting time on the extraction rate of rhenium and whether acetone should be washed by NaOH after extraction were studied. The optimized experiment condition provides high rhenium extraction rate and high separation rate of other metal elements. |
