【Abstract】 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.更多还原
