    • 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.
    • 用于检测和测量水性介质中的金属离子的检测系统包括提供机械稳定性并且尺寸和形状以拦截光束(例如,紫外线,可见光或红外区域中的光束)的基板。 反应性材料附接到基底,例如附着到基底的表面或涂覆在基底上的膜。 反应性材料能够与金属离子反应并且在反应时改变其光谱。 例如,在一个实施方案中,反应性材料包括与金属离子键合以形成螯合络合物的螯合剂。 检测系统还包括产生光束的光谱仪,其通过反应性材料到光谱仪的检测器。 例如,光谱仪可以是基于傅立叶变换,色散或滤光器的光谱仪。 反应性材料的光谱的改变允许光谱仪检测和测量金属离子。
