A new catalytic-fluorescence determination of trace copper(Ⅱ) has been established by reagent 7-(8-hydroxy-3, 6-disulfonaphthylazo)-8- hydroxyquinoline-5-sulfonic acid, and the experimental conditions have been optimized by multi-object punish function sinplex method, they are 0.05% HSNA8Q5S 1.3mL, 0.1mol/L NaOH 6.2mL, 0.1%KIO4 1.6mL, T 15min. The mechanism of the reaction has been studied. The method is applied to determine trace Copper(Ⅱ) in water sample and alloy samples with satisfactory results.
