Comprehensive Study on Extraction of Rhenium with Acetone in Re-Os Isotopic Dating

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.
