A selective optical chemosensor for iron (III)‎ ions in aqueous medium based on [bis (2, 2-bipyridine)‎-bis (2-carboxypyridine)‎] ruthenium (II)‎ complex

الملخص EN

The ruthenium (II) complex (cis-[bis (2, 2`-bipyridine)-bis (2-carboxypyridine)] ruthenium (II) Bis (hexafluorophosphate) has been synthesized and characterized using standard analytical and spectroscopic techniques, FTIR, 1H and 13C-NMR, UV / vis, elemental analysis, conductivity measurements and potentiometric titration.

Investigation of the synthesized complex with metal ions showed that this complex has absorption properties that are selective and sensitive toward the presence of iron (III) ion in an aqueous solution.

The detection limit for Fe (III) ion using UV / vis spectroscopy is estimated to be ~ 0.1 ppm.

The results presented herein have important implication in the development of an optical selective detection for iron (III) ions in aqueous solution.
