摘要: 有机高分子Schiff碱对金属离子的螯合作用已引起人们的兴趣[1,2]。硅胶为无定形高比表面无机高分子,通过氯甲基化,可进行多种化学反应而形成各种表面基团[3]。本文报道四种新型硅胶表面Schiff碱(图1),考察了它们对Cu2+,Co2+,Cd2+和Pb2+的配位作用。

Abstract: Several Schiff base supported silicas have been prepared and their adsorption capacitiesfor metal ions were measured. compared to the Schiff-base-free silica the adsorption capacityof the functionalized ones were greatly improved in the order:Cu2+>Co2+>Cd2+>Pb2+.The Nls photoelectron spectrum of Cu2+ complex with surface Schiff base was quitedifferent from that of Cu2+ ion-free surface Schiff base. Owing to the more extensiveback-bonding in the metal-coordinated - N = C - group, the Nls binding energy is far lowerfor the coordinated group than for the free one.
