以环氧溴丙烷作重原子微扰剂不经除氧环糊精诱导室温磷光法测定痕量α-溴代萘的研究

Study on Using Epibromohydrin as an External Heavy Atom Perturber Without Deoxygenation Determining α-BrN by Cyclodextrin Induced-Room Temperature Phosphorimetry

本文报道以环氧溴丙烷作重原子微扰剂，不经除氧，环糊精诱导痕量α－溴代萘的室温磷光。详细讨论了β－ＣＤ－ＥＢＨ－α－ＢｒＮ形成包接配合物的几种实验条件。结果表明，α－ＢｒＮ浓度与ＲＴＰ之间在三个数量级范围内呈良好的线性关系。

Room temperature phosphorescence(RTP) of α-Bromonaphthalene(α-BrN)is induced by β-Cyclodextr(β-CD)in fluid free from without deoxygenation in the presen of Epibromohydrin(EBH)as avaluable external heavy atom perturber.Several experimential conditions of β-CD-EBH-α-BrN for forming inclusion complex are discussed in detail Calibration curve are linear over 6×10 -8 mol/L～2×10 -6 mol/L.
