title: [Absorption characteristics of the isochromatic dye ion-pair formed by tetrabromofluorescein and buthylrhodamine B].
abstract: Absorption properties of tetrabromofluorescein (TBF) and buthylrhodamine B (BRB) and the isochromatic dye ion-pair formed by TBF and BRB were studied. The experiment showed that the proportion of TBF: BRB was 1:2 at pH=7 with Ksp = 2.16 x 10(-18), and the extraction rate was 84.2%. This provides a basis for the application of TBF and BRB to extraction spectrophotometry.
