Optical detection of cyanide by palladium(II)-dithiazolopyridine probe at the parts per billion level
The ensemble of 2,6-bis(2-chlorophenyl)dithiazolo[4,5-b:5′,4′-e]pyridine 1 with Pd2+ ions (1 center dot Pd2+) was prepared for the detection of cyanide ions (CN over bar ) in 50% aqueous methanol. Among the tested metal ions, only Pd2+ sensitively induced the red shift of the absorption bands and the complete decrease of fluorescence emission. The detection limit toward Pd2+ was 2 ppb. The ensemble 1 center dot Pd2+ selectively and rapidly detected a low concentration of cyanide ions by a colorimetric change (40 ppb) as well as a turn-on fluorescent response (5 ppb). Job’s plot revealed the complex formation with 1:1 stoichiometry. The binding and replacement mode of 1 center dot Pd2+ and CN over bar were also confirmed by H-1 NMR titrations and IR analysis. In general, a fast and selective recognition of CN over bar is reported.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 94-44-0, you can contact me at any time and look forward to more communication. Product Details of 94-44-0.
