Abstract: The sensitized α-bromonaphthene room temperature phosphorimetry by ben-zophenone in aerated β-cyclodextrin solution is presented. The room temperture phosphores-cence is observed when benzophenone is introduced into aqueous solution containing α-bromonaphthalene and β-cyclodextrin. The results show tht the phosphorescence enhance-ment induced by benzophenone is related to the function of benzophenone as both sensitizingand space-filling agents.The affecting factors on room temperature phosphorescence havebeen studied. The linear dynamic range between the concentration of α-bromonaphthaleneand the phosphorescence intensity is 0-4×10-5 mol/L.The detection limit is 1.09× 10-9mol/L. The method has been applied to the detection of α-bromonaphthalene in artificialmixture containing α-and β-bromonaphthalene, naphthalene,phenanthrene.
