A detection system for detecting and measuring a metal ion in an aqueous medium includes a substrate that provides mechanical stability and is sized and shaped to intercept an optical beam (for example, a beam in the ultraviolet, visible or infraredregion). A reactive material is attached to the substrate, for example attached to the surface of the substrate or to a film that coats the substrate. The reactive material is capable of reacting with the metal ion and changing its optical spectrum upon reacting. For example, in one embodiment the reactive material includes a chelator that bonds to the metal ion to form a chelate complex. The detection system also includes an optical spectrometer producing the optical beam that passes through the reactive material to a detector of the spectrometer. For example, the spectrometer may be a Fourier transform, dispersive or filter based spectrometer. The changing of the optical spectrum of the reactive material allows the spectrometer to detect and measure the metal ion. |
