摘　　要：以4,6-二烷氧基-1,3-苯二磺酰氯和8-羟基喹啉为原料,三乙胺作缚酸剂,丙酮为溶剂,合成了4,6-二烷氧基-1,3-二苯磺酸喹啉-8-酯(DBDADE)。合成产物的结构采用红外(IR)光谱和核磁共振(1 H NMR)技术进行表征。利用紫外光谱法研究了DBDAD E对一些金属离子的识别作用。结果发现:DBDADE对Sn2+显示出一定的选择性,由于Sn2+和Bi 3+的协同作用,在DBDADE-Sn2+体系中加入Bi 3+后,紫外吸收光谱在324nm左右形成强烈吸收峰,说明DBDADE对Bi 3+显示出优于Sn2+的选择性。4,6-Dialkoxy-benzene-1,3-disulfonic acid diquinolin-8-yl ester（DBDADE）was synthesized using 4,6-dialkoxy-benzene-1,3-disulfonyl dichlorides and 8-hydroxyquinoline as starting materials,triethylamine as the acid binding agent,and acetone as the solvent.The product was characterized by IR,1H NMR and so on.The recognition of DBDADE for Ca2＋,Pb2＋and some transition metal ions were studied by UV spectroscopy.The primary results showed that DBDADE had some recognition capabilities for Sn2＋.Due to the synergy influence of Sn2＋and Bi 3＋,a strong absorption peak at 324 nm appeared in UV spectroscopy when adding Bi 3＋into the DBDADE-Sn2＋system,which suggested that DBDADE had better recognition ability for Bi 3＋than Sn2＋.
