【摘要】 利用水热法合成了[Co（ppda）（tib）]·4H2O配位聚合物。X单晶衍射分析表明，三链接体均苯三咪唑（tib）与钴离子配位构成二维网格面；顺式对苯二乙酸（ppda）与钴离子配位构成一维波浪线，并穿插于二维网格面，加强其稳固性；二维面之间通过π-π作用力形成复杂三维超分子网络结构。进一步研究了该配位聚合物作为吸附剂去除水中四环素（TEC）的行为与机理。结果表明，配位聚合物对四环素（TEC）的吸附量为51.394mg·g^-1；吸附数据与Langmuir模型和拟二级动力学方程具有更高的拟合程度，以此可判断吸附过程为单层化学吸附；主要的吸附作用力为配位聚合物与四环素的苯环之间的π-π相互作用；热力学研究说明该吸附是自发的吸热熵增过程。更多还原

【Abstract】 [Co（ppda）（tib）]·4（H₂O） coordination polymer was synthesized by hydrothermal method. X single crystal diffraction analysis showed that 1, 3, 5-tri（1-imidazolyl） benzene and cobalt ions formed a two-dimensional grid plane by coordination bond, while p-phenyldiacetic acid and cobalt ions formed a wavy line. The one-dimensional wavy line inserted into the twodimensional plane, enhancing the stability of the two-dimensional plane. The supramolecular network was formed through π-π interactions between two-dimensional surfaces. The removal of tetracycline（TEC） from water by the coordination polymer was further studied. The results showed that the adsorption capacity was 51.334mg·g^-1. The adsorption data fit the Langmuir model and the pseudo-second-order kinetic equation, so the adsorption process could be judged as monolayer chemisorption. The main adsorption force was the π-π interaction between the coordination polymer and the benzene ring of tetracycline. The adsorption was a spontaneous process of endothermic entropy increase by thermodynamic studies.更多还原
