Abstract
The present invention relates to a molecular-based system for the optical detection, quantification and detoxification of hexavalent chromium (Cr) by reversible metal-substrate electron transfer. More particularly, the invention provides a Crsensor device comprising a divalent osmium (Os)-, iron (Fe)- or ruthenium (R)-based pyridyl complex capable of changing its oxidation state in response to a reduction of Crat the presence of H, thereby causing a reversible and optically readable change in optical properties of said complex. The Os-, Fe- or R-based pyridyl complex used according to the invention can be used for selective detection and quantification of Cr, as well as for catalytic detoxification of Cr.
