Ferron form inclusion complex with -cyclodextrin in aqueous media at pH 3.2 with an association constant of 25 M-1. This ligand has been used for the fluorimetric determination of zirconium at trace levels. The limit of detection is 0.07 g/ml and the RSD is 5.2%. A significant improvement in selectivity is gained in the -CD method compared to the method in absence of cyclodextrin. |
