    Abstract:In the presence of Tween-80 and fluoride ion，aluminium(Ⅲ) reacts with dibromohydroxy phenylfluorone(DBH_PF) in alkanine solution to form a rose colored four_component_complex with its absorption maximum at 558 nm，and molar absorptivity of 15×105 L·mol-1·cm-1.Beers law holds in the concentration range for aluminium(Ⅲ) of 0～024 μg/mL. The proposed method proves to be sensitive and selective ......
