| 英文摘要 | [中文摘要]微量六氢吡啶(HHP)存在下,由于三元包络物α-溴代萘(-αB rN)/β-环糊精(-βCD)/HHP的形成,不经除氧就可观察到强而稳定的室温磷光(RTP)发射。详细研究了温度、pH值以及形成包络物的3种组分物质的浓度的变化对体系RTP的影响。在优化实验条件下,体系的RTP强度与-αB rN的浓度在2.0~20.0μmol/L范围内呈良好线性关系,α-B rN的检出限3.7×10-8mol/L。将所建方法用于合成样品中-αB rN的测定,实验结果表明该方法的加标回收率为92.4%;相对标准偏差小于1.57%(n=7)。[英文摘要]A strong and stable room temperature phosphorescence(RTP) emission was observed from the ternary inclusion complex of α-bromonaphthalene(α-BrN)/β-cyclodextrin(β-CD)/hexahydropyridine(HHP) without deoxygenation from solution in the presence of micro amount of HHP.The effects of temperature,pH values and the variation of concentrations of each component on RTP had been investigated.Under the optimal conditions,the analytical curve of α-BrN gives a liner dynamic range of 2.0-20.0 μmol/L with a detection limit of 3. 7 ×10- 8 mol/L. The experimental results demonstrated that the recovery of the proposed method was 92.4% with a relative standard deviation less than 1. 57% ( n = 7).; 国家自然科学基金资助项目(No20577037) |
