| 英文摘要 | ag nanoclusters (ag ncs) templated by hyperbranched polyethyleneimine (pei) with different terminal groups and molecular weights had been developed as a special optical sensor for detecting p-nitrophenol (p-np). when adding p-np into ag ncs, an obvious color change from pale yellow to deep yellow could be observed by naked eyes, accompanying with an apparent red-shift of absorption peak, and the reason was attributed to the formation of oxygen anion of p-np based on the transfer of h+ from p-np to amine groups of pei. the molecular weights of template would greatly affect the sensitivity of p-np. ag ncs capped by pei terminated ethylenediamine (eda) possessed better sensitivity than other ag ncs, showing good linear range from 5 to 140 mu m with the limit of detection as low as 1.28 mu m. most importantly, this present system displayed high selectivity toward p-np even in the presence of other nitrophenols and nitrotoluenes. this reliable method had been successfully applied for the detection of p-np in real water and soil samples.
