摘　　要：合成了标题化合物,通过元素分析、1HNMR、13CNMR、IR及UV对其结构进行了表征,利用紫外光谱法考察了标题化合物对14种金属离子的识别性、萃取性和液膜传输性,讨论了它与金属离子之间的相互作用。结果表明,标题化合物对Cr3+、Pb2+离子具有良好的选择性识别作用及优良的萃取性和液膜传输性,它与两种金属离子均形成1∶1型配合物,并可实现水样中Cr3+、Pb2+的含量分析。The pyridine amide molecule of pyridine-2,6-bis[N-（ 1＇-hydroxyethyl） carbamoyl]has been synthesized and confirmed by using elemental analysis,1HNMR,13 CNMR,IR and UV. The recognition,extraction and liquid membrane transport properties of title compound with fourteen metal ions had been investigated by the ultraviolet spectrophotometry,and followed by the discussions on the interaction between title compound and metal ions. The results showed that title compound have a good selective recognition,extraction and liquid membrane transport properties for Cr3 ＋,Pb2 ＋ions. The binding stoichiometry of title compound with two metal ions was 1∶ 1,and the concentration of Cr3 ＋,Pb2 ＋ions in water samples were determined.
