In an alkaline medium, strong CL signals were observed from the reaction of CdTe QDs and H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub>, and addition of Cu<jats:sup>2+<\/jats:sup> could cause significant CL inhibition of the CdTe QDs\u2013H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> system. In the presence of CN<jats:sup>\u2212<\/jats:sup>, Cu<jats:sup>2+<\/jats:sup> can be removed from the surface of CdTe QDs via the formation of particularly stable [Cu(CN)<jats:sub><jats:italic>n<\/jats:italic><\/jats:sub>]<jats:sup>(<jats:italic>n<\/jats:italic>\u20101)\u2013<\/jats:sup> species, and the CL signal of the CdTe QDs\u2013H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> system was efficiently recovered. Thus, the CL signals of CdTe QDs\u2013H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> system were turned off and turned on by the addition of Cu<jats:sup>2+<\/jats:sup> and CN<jats:sup>\u2212<\/jats:sup>, respectively. Further, the results showed that among the tested ions, only CN<jats:sup>\u2212<\/jats:sup> could recover the CL signal, which suggested that the CdTe QDs\u2013H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub>\u2013Cu<jats:sup>2+<\/jats:sup> CL system had highly selectivity for CN<jats:sup>\u2212<\/jats:sup>. Under optimum conditions, the CL intensity and the concentration of CN<jats:sup>\u2212<\/jats:sup> show a good linear relationship in the range 0.0\u2013650.0\u2009ng\/mL (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>\u2009=\u20090.9996). The limit of detection for CN<jats:sup>\u2212<\/jats:sup> was 6.0\u2009ng\/mL (3\u03c3). This method has been applied to detect CN<jats:sup>\u2212<\/jats:sup> in river water and industrial wastewater with satisfactory results.
