摘　　要：以2-氨基嘧啶和罗丹明B为原料,两步法反应合成一种罗丹明基荧光探针,通过荧光和紫外-可见光谱法研究探针对金属离子的检测能力。实验结果表明,该探针可以快速有效地检测锡离子,且不受其他共存金属离子的干扰。荧光/紫外-可见光谱滴定结果表明,线性关系曲线为y=657.34x-50.864（荧光强度）、y=0.153 8x-0.004 9（紫外吸收强度）,线性检测范围为0-10μmol/L,可用于溶液中锡离子的定量分析。A novel Rhodamine-based probe was synthesized under the two-steps synthesis way from 2-amino pyrimidine and Rhodamine B.The recognition properties of the probe for metal ions had been investigated by the UV-Vis and fluorescence spectrophotometry.The results showed that the probe could quickly and effectively detect Sn^4＋ without interference by other co-existing metal ions.The Fluorescence/UV-Vis titration results indicated that the linear detection range was 0 - 10 μmol/L,and the linear relationship curve was y = 657. 34 x-50. 864（ fluorescence intensity）/y = 0. 153 8 x-0. 004 9（ absorption intensity）.Hence,this probe has great potential on quantitatively analysis of tin ions in aqueous solution.
