摘　　要：After samples treatment with microwave digestion,a fluorescence method for the determination of aluminium(Ⅲ) based on the system of aluminium(Ⅲ)-ciprofloxacin-SDS was developed.In NaAc-HAc medium,aluminium(Ⅲ) reacted with ciprofloxacin and SDS to form a complex with a strong fluorescence.The fluorescence excitation and emission maxima were at 365nm and 420nm,and the linear range was 2.0×10-7mol/L～2.0×10-5mol/L with the detection limit of 1.14×10-7 mol/L.This method was applied to the determination of trace aluminium(Ⅲ) in flour food samples with satisfactory results.After samples treatment with microwave digestion, a fluorescence method for the determination of aluminium （ Ⅲ ） based on the system of aluminium （ Ⅲ ）- ciprofloxacin-SDS was developed. In NaAc-HAc medium, aluminium （Ⅲ ） reacted with ciprofloxacin and SDS to form a complex with a strong fluorescence. The fluorescence excitation and emission maxima were at 365nm and 420nm, and the linear range was 2. 0 ×10^-7 mol/L ~ 2. 0 × 10^-5 mol/L with the detection limit of 1.14 × 10^-7 mol/L. This method was applied to the determination of trace aluminium（ Ⅲ ） in flour food samoles with satisfactory results.
