摘　　要：Effect of β cyclodextrin and its derivatives on the fluorescence intensities of Al(Ⅲ) Ferron were investigated in detail.The results indicated that sensitizing effect and enhanced selectivity of the system as CTMAB and HP β CD are in coexistence,there is obvious synergistie senzitizing effect.Byusing pyrene as probe,the mechanism of the effect was discussed in the light of inclusion effect principle of the cyclodextrins.Effect of β cyclodextrin and its derivatives on the fluorescence intensities of Al(Ⅲ) Ferron were investigated in detail.The results indicated that sensitizing effect and enhanced selectivity of the system as CTMAB and HP β CD are in coexistence,there is obvious synergistie senzitizing effect.Byusing pyrene as probe,the mechanism of the effect was discussed in the light of inclusion effect principle of the cyclodextrins.
