摘要
简述了碱性体系中酮类试剂对铼的革取分离研究,研究了萃取率与萃取剂用量、体系碱性浓度以及金属离子浓度等之间的关系,并比较了含氧萃取剂及酮类试剂间对铼的革取分离的能力。而闻对铼的萃取分离已用于岩石中痕量铼的实际分析测定。
The extraction separation behavior of rhenium with ketones in alkaline system is described.The effect of amount of extracting reagent, alkalillity of the system and concentration of metal ions on the extraction rate of rhenium were studied.The abilities of extraction separation of rhenium with ketones and with oxygen-colltaining reagents were compared.The extraction separation of rhenium with acetone has been applied to the determination of rhenium in rock samples.
