【摘要】 本文提出了用丁基罗丹明 B 测定痕量钽的新方法.丁基罗丹明 B 与 T_aF₆^-络阴离子形成三元离子缔合萃取物,该缔合物被萃取后有较大的荧光值,这种方法灵敏、快速、简便,选择性好,样品中测定,结果满意.另外本文对干扰离子也作了研究.更多还原

【Abstract】 In this paper,a new method for fluorimetrie determination of traceamounts of tantalum with Butyl rhodamine B.has been developed.Butylrhodamine B reacts with TaF₆^- to form a ternary ion-associate extractivecomplex.The results show that the method is simple,sensitive,selectiveand rapid.It can be used to determine tantalum in mineral samples withsatisfactory results.The effect of divers ions on the determination oftrace amount of tantalum has also been studied.更多还原
