The RTP signal of 3.5\u2010G\u2010D was sharply enhanced upon the formation of 3.5\u2010G\u2010D\u2013Tween\u201080 micelle compound. The complex Cd<jats:sup>2+<\/jats:sup>\u20133.5\u2010G\u2010D\u2013Tween\u201080, generated in the coordination reaction between Cd<jats:sup>2+<\/jats:sup> and the tertiary amidocyanogen on the outer layer of 3.5\u2010G\u2010D in 3.5\u2010G\u2010D\u2013Tween\u201080 micelle compound, could catalyze KBrO<jats:sub>3<\/jats:sub> to oxidize 3.5\u2010G\u2010D in 3.5\u2010G\u2010D\u2013Tween\u201080, which caused the sharp quenching of the RTP signal of the system. The phosphorescence intensity change (\u0394<jats:italic>I<\/jats:italic><jats:sub>p<\/jats:sub>) of the system had a linear relationship with the content of Cd<jats:sup>2+<\/jats:sup>. Thus a new catalytic solid substrate\u2013room\u2010temperature phosphorimetry (SS\u2010RTP) for the determination of trace cadmium has been established. This highly selective and sensitive method has been applied to determine trace cadmium in biological samples with a limit of detection (LD) of 1.2 ag per spot (when the sample volume was 0.4\u2009\u03bcL per spot, the corresponding concentration was 3.0\u2009\u00d7\u200910<jats:sup>\u221215<\/jats:sup>\u2009g mL<jats:sup>\u22121<\/jats:sup>), the results agreeing with those obtained by atomic absorption spectrometry. The mechanism of catalytic SS\u2010RTP for the determination of trace cadmium was also discussed.
