Fluorescence reagent salicylic aldehyde thiosemicarbazone iS synthesized. is reagent can form coordiation compound with mercury, SO as to make this reagent produce fluoroscence extinction, when it iS at A /A~=385 nm/485 nm.Making use of this reaction,the analytical method of mercury is SO set up.When the mercury content is within the range of 0—1 00 g/L,it is linear with△IF. The detectability is 0.022 g/L. erelative standard deviation detected iS 1.9%. More than 20 kinds of coexistent components have been investigated.This method has been successfully applied tO the determination of trace mercury in wastewater and sludge.
