Novel Receptor for the Rapid Reaction and Colorimetric Detection of HSO3- in Aqueous Solutions

A novel high-yield Schiff base was designed and synthesized as an anion receptor that specifically select HSO3 anions in aqueous solutions of H20/DMSO（15：85, volume ratio）, which can be detected via colorimetry under direct visualization. The sensor exhibited different results for other anions, such...

Zusammenfassung:	A novel high-yield Schiff base was designed and synthesized as an anion receptor that specifically select HSO3 anions in aqueous solutions of H20/DMSO（15：85, volume ratio）, which can be detected via colorimetry under direct visualization. The sensor exhibited different results for other anions, such as F, CI, Br, I-, H2PO4-, AcO-, HSO4 and C104. The changes in the UV-Vis spectra also show the specific recognition of HSO3 , rather than similar anions H2PO4- and HSO4- in the same aqueous solution. The detection limit of HSO3- was 1×10-6 mol/L.
