摘　　要：利用４－溴联苯内含重原子的特性，通过外加有机溶剂对４－溴联苯的增溶作用和γ－ＣＤ腔的保护性作用，在不除氧条件下首次获得有分析意义的透明ＣＤ－ＲＴＰ体系，该体系对４－溴联苯的检测限为３．０×１０－７ｍｏｌ／Ｌ。A transparent cyclodextrin induced room temperature phosphorescence (CD RTP) system for the determination of 4 bromobiphenyl without deoxidization was developed for the first time based on the internal heavy atom effect of Br and appropriate solubilization of acetonitrile.The RTP maximum wavelength are λ ex / λ em =290/480nm.The RTP intensity is linear to bromobiphenyl concentration in the range of 5.0×10 -6 ～1 0×10 -4 mol/L and 1.0×10 -4 ～5 0×10 -4 mol/L respectively.The detection limit is 3.5×10 -7 mol/L
