Abstract: Anew catalysis-fluorescence determination method of trace iron(Ⅲ)has been de scribed by reagent alizarin red, at λex/λem=380 nm/450 nm.The experimental conditions have been optimized by multiobject punish function simplex method, which are 0.1%alizarin red 4.2 mL, 0.5 mol/L HCl 3.3 mL,saturated solution KIO4 5.7mL,temp.85 ℃,time:12.5 min, the detection limit is 0.52 ng/mL.This method is applied to determine trace iron (Ⅲ)in water sample and alloy samples with satisfactory results.

Key words: Catalysis-fluoremetry, Alizarin red, Iron(Ⅲ)
