中文摘要	owing to its high affinity with phosphate, zr(iv) can induce the aggregation of adenosine 5'-triphosphate (atp)-stabilized aunps, leading to the change of surface plasmon resonance (spr) absorption spectra and color of atp-stabilized aunp solutions. based on these phenomena, visual and spr sensors for zr(iv) have been developed for the first time. the a(660 nm)/a(518 nm) values of atp-stabilized aunps in spr absorption spectra increase linearly with the concentrations of zr(iv) from 0.5 mu m to 100 mu m (r = 0.9971) with a detection limit of 95 nm. a visual zr(iv) detection is achieved with a detection limit of 30 mu m. the sensor shows excellent selectivity against other metal ions, such as cu2+, fe3+, cd2+, and pb2+. the recoveries for the detection of 5 mu m, 10 mu m, 25 mu m and 75 mu m zr(iv) in lake water samples are 96.0%, 97.0%, 95.6% and 102.4%, respectively. the recoveries of the proposed spr method are comparable with those of icp-oes method.
