摘要
应用ICP-OES测定矿样中铼,样品经过碱熔水浸取,过滤得到的滤液用环己酮萃取分离,水和三氯甲烷反萃取后得到的水相,酸化后,进行铼的测定。着重讨论了萃取分离的必要性和Mo对铼的干扰,并通过各种参数条件的优化选择进行了铼的测定,取得满意结果。本法准确度高,灵敏度高,分析线性宽,分析速度快,测定范围为0.5-100μg/mL,RSD在2.57%—6.81%之间。
The amount of rhenium in ore sample was treated by alkali fusion,filtered.The filtrate was extracted by cyclohexanone.The aqueous phase was obtained by chloroform re-extraction to remove the acidified molybdenum interference.The parameters were optimized for the selective determination of rhenium.This method is accurate and sensitive,fast with a wide linear range of 0.5—100μg/mL.
