摘要
本文提出了一个荧光法测定痕量铟(Ⅲ)的新方法,丁基罗丹明B与InBr_4^-反应,形成三元离子缔合萃取物,本法比较灵敏,快速,简捷,选择性好,应用于样品中痕量铟的测定,结果满意,文中对于干扰离子作了研究。
In this paper, a new method for fluorometric determination of traceamounts of indium has been proposed. Butyl rhodamine B reacts withInBr_4^- to from a ternary ion-association extraction. This is a simple,rapid, comparatively sensitive method, which is used to determine traceamount of indium in samples with satisfactory results. The effect ofdiverse ions was also studied.
